That would be nice to move this driver to drivers/cpuidle.

If you are ok with that, I can take care of moving the driver to this
directory and then create the pm.c file in the mach-ux500 to move the
prcmu specific code inside. Meanwhile this patch can be merged to group
the prcmu code needed for the driver and can be easily identified.
