snd_hdac_ext_stop_streams() has really nothing to do with the
extension, it just loops over the bus streams.

Move it to the hdac_stream layer and rename to remove the 'ext'
prefix and add the precision that the chip will also be stopped.

Change looks good. I wonder though, if there is a better 'name' for the 
process (here, stop streams + stop chip as a tear down process) than 
'stop_streams_and_chip'.
