[HEAD, ARM LINUX] opl_numchips=2 for opl3 cores error

[Csonicgo]

Using any of the OPL3 cores, Setting "number of OPL chips" to 2 does nothing. setting it to three is akin to "2". MAME OPL2 core doubles , triples, etc., properly.

I checked based on "STAT MUSIC" in the console and noticed that the number of channels for OPL3 cores is still 18 when numchips is 2.

For purposes of keeping the number of OPL voices from varying when switching between the OPL2 core and the OPL3 cores, opl_numchips always counts OPL2 cores. One OPL3 counts as two OPL2s.

So what do we do then? "number of voice registers", I guess? OPL3s could run in Doom in OPL2 mode, I suppose 9 voices for the OPL3 cores could be possible.
