[POWERPC] Maple: use mmio nvram
Some systems supported by the maple platform (e.g. JS2x blades running
SLOF) are able to use the mmio_nvram backend for reading and writing
nvram. This is an improvement over the current situation -- no nvram
access from userspace at all.
Select MMIO_NVRAM for the maple platform.
Initialize the mmio_nvram backend from maple setup code.
