SLOF: Support PAPR NVRAM RTAS callsqemu-slof-20121018
BenH still need to ACK this though.
From: Nikunj A. Dadhania <nikunj@linux.vnet.ibm.com>
* Determines size of the flash using device tree.
* Provides nvram access functions for RTAS_NVRAM
* Allocates temporary buffer of nvram in SLOF code and use that in C.
(sbrk not available)
* NVRAM_LENGTH is used at various places, make sure it is well guarded
and also use dynamically determined size once an RTAS-NVRAM is
found.
* Use NVRAM_LENGTH as a variable in case of RTAS_NVRAM, not very
elegant though

* #define cleanups suggested by Thomas/Benh
