DPI driver gets currently the vdds_dsi regulator via omapdss device.
This is not correct, and we'll change the DPI driver to get the
regulator directly via omapdss_dpi.0 device.
This patch changes the relevant board files to add vdds_dsi supply for
omapdss_dpi.0 device.
Note that the vdds_dsi supply for omapdss device is still left there, as
the current display driver uses it. When both the board files and the
display driver has been changed, we can remove the unused supply.

board-cm-t35.c and board-ldp.c contain regulator supply entries for
vdds_dsi. However, the given device name is wrong.
This patch fixes the device name from omapdss_dsi1 to omapdss_dsi.0.
Note that as far as I know, DSI driver is not used on these boards, so
this should not have caused any problems. The DSI block can be used to
generate clock for DPI, though, but that's not enabled for omap3 boards
currently.

The ldp board file currently requests gpios required to configure the NEC DPI
panel, and provides platform_enable/disable callbacks to configure them.
These tasks have been moved to the generic dpi panel driver itself and shouldn't
be done in the board files.
Remove the gpio requests and the platform callbacks from the board file.

Structs for platform data of omapdss panels are found in headers in the
'include/video/' path. Board files populate these structs with platform
specific values, and the panel driver uses these to configure the panel.
Currently, each panel has it's own header in the above path. Move all the
omapdss panel platform data structs to a single header omap-panel-data.h.
This is useful because:
- All other omapdss panel drivers will be modified to use platform data. This
would lead to a lot of panel headers usable only by omapdss. A lot of these
platform data structs are trivial, and don't really need a separate header.
- Platform data would be eventually removed, and platform information would be
passed via device tree. Therefore, omapdss panel platform data structs are
temporary, and will be easier to remove if they are all in the same header.
- All board files will have to include the same header to configure a panel's
platform data, that makes the board files more consistent.

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning

As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.
Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.
The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.
Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.
Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.
Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.
While at it, also sort some of the includes in the standard way.

Otherwise omap_device_build() and omap_mux related functions
can't be marked as __init when twl is build as a module.
If a board is using GPIO pins or regulators configured by an
external chip, such as TWL PMIC on I2C bus, the board must
mark those MMC controllers as deferred. Additionally both
omap_hsmmc_init() and omap_hsmmc_late_init() must be called
by the board.
For MMC controllers using internal GPIO pins for card
detect and regulators the slots don't need to be marked
deferred. In this case calling omap_hsmmc_init() is sufficient.
Only mark the MMC slots using gpio_cd or gpio_wd as deferred
as noted by Igor Grinberg <grinberg@compulab.co.il>.
Note that this patch does not change the behaviour for
board-4430sdp.c board-omap4panda.c. These boards wrongly
rely on the omap_hsmmc.c init function callback to configure
the PMIC GPIO interrupt lines on external chip. If the PMIC
interrupt lines are not configured during init, they will
fail.

This means that we can initialize the sys_timer with the .timer
