ALSA: opti93x: set MC indirect registers base from PnP data
The PnP data on the OPTI931 and OPTI933 contains io port range for the MC indirect registers. Use the PnP range instead of hardwired value 0xE0E. Also, request region of MC indirect registers so it is marked as used to other drivers (this was missing previously).
