multiplatform build.
Move the arch-specific configuration out of arch/arm/Kconfig and
into mach-davinci/Kconfig. Remove the sub-menu for DaVinci

<generated/ti-pm-asm-offsets.h> is only generated and included by
arch/arm/mach-omap2/, so it does not need to reside in the globally
visible include/generated/.
I renamed it to arch/arm/mach-omap2/pm-asm-offsets.h since the prefix
'ti-' is just redundant in mach-omap2/.
My main motivation of this change is to avoid the race condition for
the parallel build (-j) when CONFIG_IKHEADERS is enabled.
When it is enabled, all the headers under include/ are archived into
kernel/kheaders_data.tar.xz and exposed in the sysfs.
In the parallel build, we have no idea in which order files are built.
- If ti-pm-asm-offsets.h is built before kheaders_data.tar.xz,
the header will be included in the archive. Probably nobody will
use it, but it is harmless except that it will increase the archive
size needlessly.
- If kheaders_data.tar.xz is built before ti-pm-asm-offsets.h,
the header will not be included in the archive. However, in the next
build, the archive will be re-generated to include the newly-found
ti-pm-asm-offsets.h. This is not nice from the build system point
of view.
- If ti-pm-asm-offsets.h and kheaders_data.tar.xz are built at the
same time, the corrupted header might be included in the archive,
which does not look nice either.
This commit fixes the race.

Recent changes to the Atheros at803x driver cause
the approach taken here to stop working because
commit 6d4cd041f0
("net: phy: at803x: disable delay only for RGMII mode")
and commit cd28d1d6e5
("net: phy: at803x: Disable phy delay for RGMII mode")
fix the AR8031 driver to configure the phy's (RX/TX)
delays as per the 'phy-mode' in the device tree.
In particular, the phy tx (and rx) delays are updated
again as per the 'phy-mode' *after* the code in here
runs.
Things worked before above commits, because the AR8031
comes out of reset with RX delay enabled, and the
at803x driver didn't touch the delay configuration at
all when "rgmii" mode was selected.
It appears the code in here tries to make device
trees work that incorrectly specify "rgmii", but
that can't work any more and it is imperative since
above commits to have the phy-mode configured
correctly in the device tree.
I suspect there are a few imx7d based boards using
the ar8031 phy and phy-mode = "rgmii", but given I
don't know which ones exactly, I am not in a
position to update the respective device trees.
Hence this patch is simply removing the superfluous
code from the imx7d initialisation. An alternative
could be to add a warning instead, but that would
penalize all boards that have been updated already.

"MICROCHIP TIMER COUNTER (TC) AND CLOCKSOURCE DRIVERS" is better
removed because one file entry is outdated and basically, the
maintainer's pool of Alexandre, Ludovic and myself is better suited.
drivers/misc/atmel_tclib.c file is going away in a patch to come and
drivers/clocksource/tcb_clksrc.c file is actually named timer-atmel-tcb.c.
This new name matches the AT91 entry regular expression.

<generated/at91_pm_data-offsets.h> is only generated and included by
arch/arm/mach-at91/, so it does not need to reside in the globally
visible include/generated/.
I renamed it to arch/arm/mach-at91/pm_data-offsets.h since the prefix
'at91_' is just redundant in mach-at91/.
My main motivation of this change is to avoid the race condition for
the parallel build (-j) when CONFIG_IKHEADERS is enabled.
When it is enabled, all the headers under include/ are archived into
kernel/kheaders_data.tar.xz and exposed in the sysfs.
In the parallel build, we have no idea in which order files are built.
- If at91_pm_data-offsets.h is built before kheaders_data.tar.xz,
the header will be included in the archive. Probably nobody will
use it, but it is harmless except that it will increase the archive
size needlessly.
- If kheaders_data.tar.xz is built before at91_pm_data-offsets.h,
the header will not be included in the archive. However, in the next
build, the archive will be re-generated to include the newly-found
at91_pm_data-offsets.h. This is not nice from the build system point
of view.
- If at91_pm_data-offsets.h and kheaders_data.tar.xz are built at the
same time, the corrupted header might be included in the archive,
which does not look nice either.
This commit fixes the race.

Enable low-level debugging support for RZ/A2M (r7s9210).
The RZA2MEVB board uses either SCIF2 (SDRAM enabled) or SCIF4 (HyperRAM
only) for the serial console.
Note that "SCIFA" serial ports on RZ/A2 SoCs use a compressed register
layout, hence add support for that to renesas-scif.S.

The lpc_eth driver uses a platform specific method to find
the internal sram. This prevents building it on other machines.
Rework to only use one function call and keep the other platform
internals where they belong. Ideally this would look up the
sram location from DT, but as this is a rarely used driver,
I want to keep the modifications to a minimum.

The driver hardcodes a hardware I/O address the way one should
generally not do, and this prevents both compile-testing, and
moving the platform to CONFIG_ARCH_MULTIPLATFORM.
Change the code to be independent of the machine headers
to allow those two. Removing the hardcoded address would
be hard and is not necessary, so leave that in place for now.

In a multiplatform configuration, enabling DEBUG_LL breaks booting
on all platforms with incompatible settings. In case of the Marvell
platforms of the Orion/MVEBU family, the physical addresses are
all the same, we just map them at different virtual addresses,
which makes it impossible to run a kernel with DEBUG_LL enabled on
a combination of the merged mvebu and the legacy boardfile based
platforms.
This is easily solved by using the same virtual address everywhere.
I picked the address that is already used by mach-mvebu for UART0:
0xfec12000. All these platforms have a 1MB region with their internal
registers, almost always at physical address 0xf1000000, so I'm
updating the iotable for that entry.
In case of mach-dove, this is slightly trickier, as the existing
mapping is 8MB and a second 8MB mapping is already at the 0xfec00000
address. I have verified from the datasheet that the last 7MB of the
physical mapping are "reserved" and nothing in Linux tries to use
it either. I'm putting this 1MB mapping at the same address as the
others, and the second 8MB register area immediately before that.

This is a simple move of all header files that are no longer
included by anything else from the include/mach directory
to the platform directory itself as preparation for
multiplatform support.
The mach/uncompress.h headers are left in place for now,
and are mildly modified to be independent of the other
headers. They will be removed entirely when ARCH_MULTIPLATFORM
gets enabled and they become obsolete.
Rather than updating the path names inside of the comments
of each header, I delete those comments to avoid having to
update them again, should they get moved or copied another
time.

Various bits of iop32x are now in their traditional locations in plat-iop,
mach-iop/include/mach/ and in include/asm/mach/hardware. As nothing
outside of the iop32x mach code references these any more, this can all
be moved into one place now.
The only remaining things in the include/mach/ directory are now the
NR_IRQS definition, the entry-macros.S file and the the decompressor
uart access. After the irqchip code has been converted to SPARSE_IRQ
and GENERIC_IRQ_MULTI_HANDLER, it can be moved to ARCH_MULTIPLATFORM.
