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".

The pm-imx27.c references a number of things requiring the explicit
inclusion of mach/hardware.h.  Otherwise, when indirect inclusion
to mach/hardware.h gets cleaned up, we will see the following
compile error.

This patch adds an idle hook imx_idle to be called in arch_idle().
Any soc that needs a customized idle implementation other than
cpu_do_idle() can set up this hook in soc specific call.

Code called from an initcall can be maybe called for
machines it's not intended for. So check for valid
machines and return gracefully if an incompatible machine
is found.

While at it, fix two checkpatch errors.
Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should
be const" structs (79404849).

Patch against mainline.
Inspired by hunks of the grsecurity patch, updated for newer kernels.
