This adds support for the mixer and wavetable synthesizer of OPL4 chips. The OPL4 can be used with OPTi 82C928/Mozart, 82C929 and 82C924 cards (82C925 and 82C93x have an integrated OPL3 and don't support an external OPLx chip).

The changes in alsa-kernel/drivers/opl3/*.c involve modifications of the OPL3's mode register which would clear the NEW2 bit (which enables OPL4 registers). Those register writes had been used to restrict the OPL3 to OPL2 compatibility, which IMHO isn't necessary, so I removed them. :) Clemens
