Instead of __raw_*, define imx_* to *_relaxed and use those.
Using imx_* was requested by Arnd because *_relaxed tends to
indicate that the code was carefully reviewed to not require
any synchronisation and otherwise be safe, which isn't the
case here with the automatic conversion.
The conversion itself was done using the following spatch
(since that automatically adjusts the coding style unlike
a simple search&replace).

Migrate imx driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
Also drop 'clockevent_mode': It was caching the last state of the
clockevent device. The same behavior can be achieved by using
clockevents state helpers. These helpers are only required for oneshot
mode as shutdown/resume wouldn't be done twice by the core.

The clockevent core is able to figure out the best mult and shift,
calculate min_delta_ns and max_delta_ns, with the necessary info passed
into clockevents_config_and_register(). Use this combined configure
and register function where possible to make the codes less error prone
and gain some positive diff stat.

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".

Rename mach-imx/include/mach/common.h to mach-imx/common.h and update
all users to include common.h rather than mach/common.h.
It also removes an unneeded inclusion to common.h in
mach-imx/devices/devices.c.

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.
