Nouveau - Jan 2024 - [PATCH 1/6] drm/nouveau: convert to using is_hdmi and has_audio from display info

Prefer the parsed results for is_hdmi and has_audio in display info over
calling drm_detect_hdmi_monitor() and drm_detect_monitor_audio(),
respectively.

Conveniently, this also removes the need to use edid_blob_ptr.

Conveniently, this also removes the need to use edid_blob_ptr.
