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 Zhao <chenhui.zhao@freescale.com> Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> [scottwood: remove __KERNEL__ ifdef] Signed-off-by: Scott Wood <oss@buserror.net>
