Only mx508 based board is mach-mx50_rdp and it has been marked as BROKEN
for several releases.

mx508 currently lacks clock support.

In case someone needs to add mx508 support back, then the recommended approach
is to use device tree.

It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h.  The files in mach-imx/devices
will need to include "../hardware.h".

It's really unnecessary to have plat-mxc, and let's merge it into
mach-imx.  It's pretty much just a bunch of file renaming and
Kconfig/Makefile merge.

To make the change less invasive, we keep using Kconfig symbol
CONFIG_ARCH_MXC for mach-imx sub-architecture.

A change is needed in the IMX_IO_P2V macro to allow all imx5 platforms
to use common definitions when accessing registers of peripherals on
the AIPS2 bus.  With this change, IMX_IO_P2V(MX50_AIPS2_BASE_ADDR) ==
IMX_IO_P2V(MX51_AIPS2_BASE_ADDR) == IMX_IO_P2V(MX53_AIPS2_BASE_ADDR).

This change was tested for mapping conflicts using the iop2v script
found at git://git.pengutronix.de/git/ukl/imx-iop2v.git and by
performing a bootup of a default build using imx_v6_v7_defconfig
on a imx51 babbage board and imx53 loco board.  The comments were
modified to reflect the output given by the script which shows the
virtual address mappings.

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image
the ioremap quirk needs a runtime check.

While touching this code make the comment more understandable by adding
a sentence from the commit log that introduced it
(eadefeff ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)).

As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h
was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which
#includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros
needs to be included before mach/mx27.h and mach/mx31.h.)
