drm/amd/display: adjust flow for deallocation mst payload
[Why]
MST relevant variables are maintained at drm side. As the result, we
still have to call drm_dp_remove_payload_part2() to update the relevant
values regardless the link is under mst mode or not. We used to have a
workaround patch to tackle this: commit 3d8fcc6740c9 ("drm/amd/display:
Extract temp drm mst deallocation wa into its own function")
Now it's time to remove the workaround and adjust the flow.
[How]
During deallocate_mst_payload(), source actually doesn't send out
ALLOCATE_PAYLOAD at the end as like the flow in allocate_mst_payload().
Call function dm_helpers_dp_mst_send_payload_allocation() at the end of
deallocate_mst_payload() is a bit confusing.
Separate dm_helpers_dp_mst_send_payload_allocation() into 2 functions.
Have a new function dm_helpers_dp_mst_update_mst_mgr_for_deallocation()
to replace dm_helpers_dp_mst_send_payload_allocation() for payload
deallocation.
