[Why & How]
This commit is part of a sequence of changes that replaces the commit
sequence used in the DC with a new one. As a result of this transition,
we moved some specific parts from the commit sequence and brought them
to amdgpu_dm. This commit adds a wrapper inside DM that enable our
drivers to do any necessary preparation or change before we offload the
plane/stream update to DC.
