[PATCH v3 3/5] ASoC: Intel: avs: Ignore codecs with no suppoting driver

[Cezary Rojewski]

HDMI codecs which are present and functional from audio perspective lack
i915 support on drm side what results in -ENODEV during the probing
sequence. There is no reason to perform recovery procedure e.g.: reset
the HDAudio controller if this is the case.
