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.

Add various functionality needed to enable a imx53 low power idle
state. This includes adding the imx53 gpc_dvfs clock and making a
common imx5_late_init function and initializing all imx53
MACHINE_STATE late_init calls to imx5_late_init.

The imx5 idle code that existed in mm-imx5.c is moved to pm-imx5.c.
The imx5_pm_init call is now exported and called during the
MACHINE_START late_init in supported imx5 platforms.
Remove various enabling/disabling of the gpc_dvfs clock and
enable it once during initialization. This is a very low
power clock that must be enabled during low power operations.
There are only two "suspend_state_t" imx5 low power modes ever
used. STOP_POWER_OFF for suspend to mem and
WAIT_UNCLOCKED_POWER_OFF for idle and suspend to standby. The
latter mode only requires 500 nanoseconds of extra hardware
exit time beyond a basic WFI operation (WAIT_CLOCKED mode) so
no other idle mode is necessary. Given this information, it
is more efficient to keep the registers in the often used
WAIT_UNCLOCKED_POWER_OFF state and only to and from the
STOP_POWER_OFF register state as needed when suspend to
mem is required.

Merge tag 'arm-soc-imx-move' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Consolidate i.MX 5 platforms to be under the new shared i.MX 3/5/6 tree.
* tag 'arm-soc-imx-move' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
ARM i.MX: Update defconfig
ARM i.MX: Merge i.MX5 support into mach-imx
ARM i.MX5: remove unnecessary includes from board files
Fix up fairly trivial conflicts due to various changes nearby in
arch/arm/{mach,plat}-imx/{Kconfig,Makefile}
Pull request had been sent to the wrong email address, but happened
before the merge window closed. I'm merging the MX 5 consolidation,
since it apparently will help the next development window and will avoid
conflicts later as per Arnd.
This patch moves the contents of arch/arm/mach-mx5 to arch/arm/mach-imx
and adjusts the Makefile/Kconfig entries in a way that it's possible
to compile i.MX5 together with i.MX3/6.
