sof-hda-dsp: don't fail if Auto-Mute control is not present

[GitHub pull_request - opened]

alsa-project/alsa-ucm-conf pull request #33 was opened from kv2019i:

The "Auto-Mute Mode" control is not present in all HDA codecs.
The generic SOF HDA UCM file should be robust enough to handle
these cases as well.
