Patches looks fine as it is, but do you realize that this s a dead code 
w.r.t upstream.
WSA2 is used only with 4 speaker setup and in such cases we use WSA 
codec dma to drive 4 channels.

So WSA2 will not be used by itself.
I would prefer support for this to be added when we are really able to 
test WSA2 by itself.

thanks,
Srini
