This patch fixes the initialisation and reset of the tas codec. The tas will often reset if the i2s clocks go away so it needs to be completely re-initialised when clocks come back. Also, this patch adds some code for DRC that will be exploited later to add a DRC control again, fixing a regression over snd-powermac.
