drm/i915: Fix audio component initialization
After registering the audio component in i915_audio_component_init()
the audio driver may call i915_audio_component_get_power() via the
component ops. This could program AUD_FREQ_CNTRL with an uninitialized
value if the latter function is called before display.audio.freq_cntrl
gets initialized. The get_power() function also does a modeset which in
the above case happens too early before the initialization step and
triggers the
"Reject display access from task"
error message added by the Fixes: commit below.
Fix the above issue by registering the audio component only after the
initialization step.
Fixes: 87c1694533c9 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend")
Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10291
