pseries: Implement PAPR NVRAM
The PAPR specification requires a certain amount of NVRAM, accessed via
RTAS, which we don't currently implement in qemu. This patch addresses
this deficiency, implementing the NVRAM as a VIO device, with some glue to
instantiate it automatically based on a machine option.
The machine option specifies a drive id, which is used to back the NVRAM,
making it persistent. If nothing is specified, the driver instead simply
allocates space for the NVRAM, which will not be persistent
