[Suraj Kandpal]

Now that drm_writeback_connector is embedded with the drm_connector
adapt the amd writeback functionality to this changes. This includes
changing the drm_writeback_connector to be changed to drm_connector
within the amdgpu_dm_wb_connector. Some other changes are done which
are a result of the all the above changes mentioned.
