From: Cezary Rojewski <cezary.rojewski@intel.com>

commit a66f88394a78fec9a05fa6e517e9603e8eca8363 upstream.

With _reset_link removed from the probe sequence, codec_mask at the time
skl_find_hda_machine() is invoked will always be 0, so hda machine will
never be chosen. Rather than reorganizing boot flow, be permissive about
invalid mask. codec_mask will be set to proper value during probe_work -
before skl_codec_create() ever gets called.
