drm/amd/display: Add handling for DC power mode

Browse Source 
[Why]
Future implementations will require a distinction between AC power and
DC power (wall power and battery power, respectively). To accomplish this,
adding a power mode parameter to certain dc interfaces, and adding a
separate DML2 instance for DC mode validation. Default behaviour unchanged.
