drm/i915/dg1: Adjust the AUDIO power domain
DG1 and XE_PLD platforms has Audio MMIO/VERBS lies in PG0 power
well. Adjusting the power domain accordingly to
POWER_DOMAIN_AUDIO_MMIO for audio detection and
POWER_DOMAIN_AUDIO_PLAYBACK for audio playback.
While doing this it requires to use POWER_DOMAIN_AUDIO_MMIO
power domain instead of POWER_DOMAIN_AUDIO in crtc power domain mask
and POWER_DOMAIN_AUDIO_PLAYBACK with intel_display_power_{get, put}
to enable/disable display audio codec power.
It will save the power in use cases when DP/HDMI connectors
configured with PIPE_A without any audio playback.
v1: Changes since RFC
- changed power domain names. [Imre]
- Removed TC{3,6}, AUX_USBC{3,6} and TBT from DG1
power well and PW_3 power domains. [Imre]
- Fixed the order of powe wells , power domains and its
registration. [Imre]
v2:
- Not allowe DC states when AUDIO_MMIO domain enabled. [Imre]
v3:
- Squashes the commits of series to avoid build failure.
