[RFC v4 13/25] powerpc: Cleanup nvram includes

[Finn Thain <fthain@telegraphics.com.au>]

The nvram_read_byte() and nvram_write_byte() definitions in asm/nvram.h
duplicate those in linux/nvram.h. Get rid of the former to prepare for
adoption of struct arch_nvram_ops (which is defined in linux/nvram.h for
general use).
