drm_hwcomposer: Handle writeback connectors When writeback connectors are available assign them to displays, in order to be able to use them for flattening of the current displayed scene. The pipeline for each display will look like this: CRTC ---- encoder ------------ display connector. |------- writeback enc ------ writeback connector. However, the writeback connector will be later used/enabled only if one of the following conditions are met: - Could be a clone of the display connector, as pointed by the possible_clones property. - The display_connector is disconnected, so we are safe to use it for flattening the scene that's already presented on another display.
