superio/ite/it8721f: Rewrite from hardcoded base addr
Rewrite early_serial.c implementation to honour a passed base address in
device_t, removing any hard coding of values. We also expose early sio
init functions as romstage symbols to avoid falsely #including
"early_serial.c" in romstage.c of board support.
