Subject: [PATCH 046/114] x86: refactor ->setup_portio_remap() subarch methods
Only NUMAQ has a real ->setup_portio_remap() method, the other
subarchitectures define it but keep it empty.
So mark the vector as NULL, extend the generic code to handle
NULL -setup_portio_remap() entries and remove all the empty
handlers.
Also move the NUMAQ method from the header file into the
apic driver .c file.
