drm/amd/display: Request PHYCLK adjustment on PHY enable/disable
[Why]
Currently we don't explicitly send a request for a minimum PHYCLK, and
we hope that the dependencies other clocks have will raise PHYCLK when
needed.
[How]
- new clk_mgr function to keep track of PHYCLK requirements
- request maximum requirement across all links
- remove PHYCLK from clock state comparator, as it doesn't come from DML
