Takashi Iwai 96e503f900 ALSA: hda/i915 - fix list corruption with concurrent probes
Current hdac_i915 uses a static completion instance to wait
for i915 driver to complete the component bind.

This design is not safe if multiple HDA controllers are active and
communicating with different i915 instances, and can lead to list
corruption and failed audio driver probe.

Fix the design by moving completion mechanism to common acomp
code and remove the related code from hdac_i915.

Fixes: 7b882fe3e3 ("ALSA: hda - handle multiple i915 device instances")
