Subject: [isg-gms] [PATCH] drm/i915: Get audio power domain during initial hw readout (v2)

if the crtc has audio is enabled. Otherwise, when the first atomic modeset happens it will warn when trying to drop the audio power domain.

v2: move this to get_crtc_power_domains to be consistent with other
power domain setup (Ville)
