system/physmem: Propagate AddressSpace to MapClient helpers

Propagate AddressSpace handler to following helpers:
- register_map_client()
- unregister_map_client()
- notify_map_clients[_locked]()

Rename them using 'address_space_' prefix instead of 'cpu_'.

The AddressSpace argument will be used in the next commit.
