When loading the fw_cfg address with just lis, addi sequence, we get the high address bits as 0xffffffff on ppc64. Use the full double word immediate load sequence on ppc64. v2: * Rename from load() to LOAD_REG_IMMEDIATE() to match Linux. Suggested by Alex. * Move to ppc/asmdefs.h for future use elsewhere.
