Rename cpu_physical_memory_write_rom() to address_space_write_rom()
The API of cpu_physical_memory_write_rom() is odd, because it takes an AddressSpace, unlike all the other cpu_physical_memory_* access functions. Rename it to address_space_write_rom(), and bring its API into line with address_space_write().
