ALSA: azt3328: add custom AC97 semi-emulation use standard ALSA AC97 layer
Make use of the very flexible ALSA ac97 layer (hooks for custom I/O!)
on this weird AC97 copycat hardware,
via semi-extended I/O translation/emulation.
Some 5kB binary/loaded size saved (well... additional huge AC97 module
penalty not factored in, of course ;-P).
Given that the driver previously had 20kB that's not bad,
but the much more important thing is to have AC97 layer stress-tested
with a thoroughly weird AC97 copycat (or, simply put, if it were not for
this AC97 test aspect, this effort would merely have been a nut job ;).

Say Y here to include support for Aztech AZF3328 (PCI168)
soundcards.
+ Supported features: AC97-"conformant" mixer, MPU401/OPL3, analog I/O
+ (16bit/8bit, many sample rates [<= 66.2kHz], NO hardware mixing),
+ Digital Enhanced Game Port, 1.024MHz multimedia sequencer timer,
+ ext. codec (I2S port), onboard amp (4W/4Ohms/ch), suspend/resume.
+
To compile this driver as a module, choose M here: the module
will be called snd-azt3328.
