The revision definitions and declarations are widely used by clock
drivers.  As a step of moving clock drivers out of arch/arm/mach-imx,
let's create header include/soc/imx/revision.h to accommodate them.

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.

As all irqchips on imx have been changed to allocate their irq_descs,
and all unneeded mach/irqs.h inclusions on imx have been cleaned up,
now it's time to select SPARSE_IRQ for imx/mxc.

The SPARSE_IRQ support forces irqs allocation starting from 16.  All
those static irq number definition for SoCs need to shift 16 to keep
non-DT boot works.

With all those static IRQ number and start definitions removed from
mach/irqs.h, the header becomes just a container of a couple of
mach-imx specific irq/fiq calls.  Since mach/irqs.h is not included
by asm/irq.h now, the users of mxc_set_irq_fiq needs to explicitly
include mach/irqs.h themselves.

The helper function mx27_setup_weimcs() references IOMEM() and
IMX_IO_P2V() but without required header mach/hardware.h included
in mx27.h.  This will break the build of those mx27 file with no
direct inclusion of mach/hardware.h, or when indirect inclusion to
mach/hardware.h breaks.

For example, when the inclusion of mach/hardware.h gets removed from
mach/gpio.h, we will see the following compile error.

  CC      arch/arm/mach-imx/pm-imx27.o
In file included from arch/arm/mach-imx/pm-imx27.c:14:0:
arch/arm/plat-mxc/include/mach/mx27.h: In function ‘mx27_setup_weimcs’:

arch/arm/plat-mxc/include/mach/mx27.h:138:2: error: implicit declaration of function ‘IMX_IO_P2V’

This patch removes mx27_setup_weimcs() from mx27.h and makes it local
to mach-pcm038.c, which is the only user for this helper.

This makes it more assembler friendly and allows it to be used in situation
that need an unsigned long and not a pointer.  Also the naming is
clearer.  IOMEM is introduced without IMX_ prefix as it is used this way
in more than one ARM subarch and it might become globally available
soon.
