From: Joshua Ashton <joshua at froggi.es>
Implements the 'content type' property for HDMI connectors.
Verified by checking the avi infoframe on a connected TV.
This also simplifies a lot of the code in that area as well, there were
a lot of temp variables doing very little and unnecessary logic
that was quite confusing.
It is not necessary to check for support in the EDID before sending a
'content type' value in the avi infoframe also.
v2:
- rebase to amd-staging-drm-next
- mark CRTC state for reset if content_type differs
