powerpc/powernv: Add RTC and NVRAM support plus RTAS fallbacks
Implements OPAL RTC and NVRAM support and wire all that up to the powernv platform. We use RTAS for RTC as a fallback if available. Using RTAS for nvram is not supported yet, pending some rework/cleanup and generalization of the pSeries & CHRP code. We also use RTAS fallbacks for power off and reboot Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
