powerpc/rcpm: add RCPM driver

There is a RCPM (Run Control/Power Management) in Freescale QorIQ
series processors. The device performs tasks associated with device
run control and power management.

The driver implements some features: mask/unmask irq, enter/exit low
power states, freeze time base, etc.
