drm/amd/display: Disable DRR actions during state commit

[ Upstream commit de020e5fa9ebc6fc32e82ae6ccb0282451ed937c ]

[WHY]
Committing a state while performing DRR actions can cause underflow.

[HOW]
Disabled features performing DRR actions during state commit.
Need to follow-up on why DRR actions affect state commit.
