[ALSA] Add snd_card_set_generic_dev() call to ISA drivers

ISA,CMI8330 driver,ES18xx driver,OPL3SA2 driver,Sound Galaxy driver
Sound Scape driver,AD1848 driver,CS4231 driver,CS4236+ driver
ES1688 driver,GUS Classic driver,GUS Extreme driver,GUS MAX driver
AMD InterWave driver,Opti9xx drivers,SB16/AWE driver,SB8 driver
Wavefront drivers
- Added snd_card_set_generic_dev() call.
- Added SND_GENERIC_DRIVER to Kconfig.
- Clean up the error path in probe if necessary.
