[ALSA] opti9xx: adjust OPL3 FM resource value

Browse Source 
The OPTi ISA-PnP chips advertise their OPL4 base at 0x380 (to 0x3f0) through
pnp and put their on-chip OPL3 at +8. The driver assumes the provided
value is the ALBase (OPL3 address) though and checks for an OPL4 at -8,
which means that simply adding 8 to the pnp provides value works to fix
detection of both OPL3 and OPL4.
Problem spotted on 931 and 933 by Krzysztof Helt and confirmed on 924 and
925 (together all OPTi ISA-PnP chips) by me.
