[Intel-gfx] [RFC 1/4] drm/i915/hdmi: Add audio config related params in crtc_state

[Mitul Golani <mitulkumar.ajitkumar.golani@intel.com>]

Add source audio-related config params in crtc_state.
These params can be supported frequency, supported channel,
and audio support, which can be further computed based on
source capabilities.
