Make use of arch_nvram_ops in device drivers so that the nvram_* function exports can be removed.
Since they are no longer global symbols, rename the PPC32 nvram_* functions appropriately.

Instead of modifying all drivers (in this patch and previous ones related to other arches), wouldn't it be better to add helpers like the following in nvram.h:
Static inline unsigned char nvram_read_byte(int addr) { return arch_nvram_ops.read_byte(addr); }
