Subject: [PATCH v3 4/9] ALSA: hda/i915: Allow xe as match for i915_component_master_match

xe is a new driver for intel GPU's that shares the sound related code
with i915.

Don't allow it to be modprobed though; the module is not upstream yet
and we should exclusively use the EPROBE_DEFER mechanism.
