Chris Park 3838c67365 drm/amd/display: On clock init, maintain DISPCLK freq
[Why]
On init if a display is connected, we need to maintain the DISPCLK
frequency Even though DPG_EN=1, the display still requires the correct
timing or it could cause audio corruption (if DISPCLK freq is reduced).

[How]
Read the current DISPCLK freq and request the same value to ensure the
timing is valid and unchanged.
