powerpc64/powernv: Add opal NVRAM driver for PowerNV systemsAdd a very basic NVRAM driver for OPAL which can be used by the IBMpowerpc-utils nvram utility, not to be confused with the base nvram utility,which only operates on powermac_nvram.The IBM utility handles all partitions itself, treating the nvram device asa plain store.An alternative would be to manage partitions in the kernel, and augment thebase nvram utility to deal with different backing stores, but thatcomplicates the driver significantly. Instead, present the same interfaceIBM's utlity expects, and we get the usage for free.Tested by: bdragon
