Benjamin Herrenschmidt 6a4f578745 [PATCH] aoa: tas: fix initialisation/reset
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.
