drm/amd/display: allow hpo and dio encoder switching during dp retrain test
[why]
During DP2.1 LL CTS if test equipment requests to change between
DP2.1 and DP1.4 link rates, we need to swap between HPO and DIO
encoders by remapping encoder resource.
[how]
Add a function dc resource to update encoder resources and toggle
dpms state for all enabled stream associated witht the link under test.
