CHROMIUM: ALSA: hda/ca0132 - Toggle DAC format when starting a stream.

Sometimes the DAC format would be incorrect after resume even if the
register indicated it was correct. Add a toggle of the format to make
sure the DAC gets audio in the format it expects.

BUG=chrome-os-parnter:17740
TEST=overnight loopback test checking for audio while suspend/resuming
the codec.
