drm/amd/display: Support AVI InfoFrame V3 and V4

Browse source

[Why]
Part of HDMI 2.1 requires AVI InfoFrame version update
from current V2 to V3 for new VICs, and V4 for
new colorimetry.

[How]
Implement V3 and V4 AVI InfoFrame.
If (C1, C0)=(1, 1) and (EC2, EC1, EC0)=(1, 1, 1),
the Source shall use 20 AVI InfoFrame Version 4.
If VIC >= 128, the Source shall use AVI InfoFrame Version 3
