ALSA: ac97: Add helper function to reset the AC97 device

Browse Source 
There is currently a lot of code duplication in ASoC drivers regarding the
reset handling of devices. This patch introduces a new generic reset
function in the generic AC'97 framework that can be used to replace most
the custom reset functions.
