ALSA: hda - Force to reset IEC958 status bits for AD codecs

commit ae24c3191ba2ab03ec6b4be323e730e00404b4b6 upstream.

Several bug reports suggest that the forcibly resetting IEC958 status
bits is required for AD codecs to get the SPDIF output working
properly after changing streams.

Original fix credit to Javeed Shaikh.
