e779f4587f drm/amd/display: Add handling for DC power mode 
[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.

cc263c3a0c drm/amd/display: remove context->dml2 dependency from DML21 wrapper 
[Why]
When the DML2 wrapper explicitly accesses context->dml2, that creates a
dependency on where dc saves the DML object. This dependency makes it
harder to have multiple co-existing DML objects, which we would like to
have for upcoming functionality.

[How]
 - make all DML21 interfaces take in a DML2 object as parameter
 - remove all references to context->dml2, use parameter instead
