Jake Wang 0a068b683c drm/amd/display: Added HPO HW control shutdown support 
[Why]
HPO is only used for DP2.0. HPO HW control should be
disable when not being used to save power.

Shutdown HPO HW control during init hw.
Shutdown HPO HW control during stream disable.
Enable HPO HW control during stream enable if DP2.0.
