m68k/mac: Adopt naming and calling conventions for PRAM routines

Browse Source 
Adopt the existing *_read_byte and *_write_byte naming convention.
Rename via_pram_readbyte and via_pram_writebyte to avoid confusion.
Adjust calling conventions of mac_pram_* functions to match the
struct nvram_ops methods.
