[PATCH v2,2/5] 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. Signed-off-by: Chenhui
