drm/amd/display: Check DP Alt mode DPCS state via DMUB [Why] Currently, driver state for DCN3.2 is not strictly matching HW state for the USBC port. To reduce inconsistencies while debugging, the driver should match HW configuration. [How] Update link encoder flag to indicate USBC port. Call into DMUB to check when DP Alt mode is entered, and also to check for 2-lane versuse 4-lane mode.
