drm/amd/display: HDMI ODM Combine Policy Correction
[WHY]
Reprogramming the stream despite no changes in ODM combine mode.
Reprogramming the stream would cause intermittent black screen on
display which could only be recovered through enable/disable sequence.
[HOW]
Fixed bug where we detected a change in ODM combine mode despite ODM
combine mode being disabled. Also removed code which required stream to
be reprogrammed once a change in ODM combine mode was noticed. Lastly we
do not support dynamic ODM switching for HDMI TMDS and FRL on DCN32,
therefore we never want to change its ODM policy.
