The new mvebu-mbus driver was not checking the device tree for
coherency fabric hardware and hence was not setting the hw_io_coherency
flag in mbus_state. This prevented the mvsdio driver from operating
correctly. This patch restores the check.

The Marvell EBU SoCs have a configurable physical address space
layout: the physical ranges of memory used to address PCI(e)
interfaces, NOR flashes, SRAM and various other types of memory are
configurable by software, through a mechanism of so-called 'address
decoding windows'.
This new driver mvebu-mbus consolidates the existing code to address
the configuration of these memory ranges, which is spread into
mach-mvebu, mach-orion5x, mach-mv78xx0, mach-dove and mach-kirkwood.
Following patches convert each Marvell EBU SoC family to use this
driver, therefore removing the old code that was configuring the
address decoding windows.
It is worth mentioning that the MVEBU_MBUS Kconfig option is
intentionally added as a blind option. The new driver implements and
exports the mv_mbus_dram_info() function, which is used by various
Marvell drivers throughout the tree to get access to window
configuration parameters that they require. This function is also
implemented in arch/arm/plat-orion/addr-map.c, which ultimately gets
removed at the end of this patch series. So, in order to preserve
bisectability, we want to ensure that *either* this new driver, *or*
the legacy code in plat-orion/addr-map.c gets compiled in.
By making MVEBU_MBUS a blind option, we are sure that only a platform
that does 'select MVEBU_MBUS' will get this new driver compiled
in. Therefore, throughout the next patches that convert the Marvell
sub-architectures one after the other to this new driver, we add the
'select MVEBU_MBUS' and also ensure to remove plat-orion/addr-map.c
from the build for this specific sub-architecture. This ensures that
bisectability is preserved.
Ealier versions of this driver had a DT binding, but since those were
not yet agreed upon, they were removed. The driver still uses
of_device_id to find the SoC specific details according to the string
passed to mvebu_mbus_init(). The plan is to re-introduce a proper DT
binding as a followup set of patches.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

These devices are not available on other architectures, so
let's limit them to omap.
If the driver subsystem maintainers want to build test
system wide changes without building for each target,
it's easy to carry a test patch that just strips out the
depends entries from Kconfig files.

ocp2scp was not having pdata support which makes *musb* fail for non-dt
boot in OMAP platform. The pdata will have information about the devices
that is connected to ocp2scp. ocp2scp driver will now make use of this
information to create the devices that is attached to ocp2scp.
This is needed to fix MUSB regression caused by commit c9e4412a

Adds a new driver *omap-ocp2scp*. This driver takes the responsibility of
creating all the devices that is connected to OCP2SCP. In the case of OMAP4,
USB2PHY is connected to ocp2scp.
This also includes device tree support for ocp2scp driver and
