ALSA: ac97: add an ac97 bus
AC97 is a bus for sound usage. It enables for a AC97 AC-Link to link one controller to 0 to 4 AC97 codecs. The goal of this new implementation is to implement a device/driver model for AC97, with an automatic scan of the bus and automatic discovery of AC97 codec devices.
