The IPUv3 DRM i.MX driver contains several codepaths for different usescases: both LDB and paralllel-display drivers handle next-bridge, panel and the legacy display-timings DT node on their own. Drop unused ddc-i2c-bus and edid handling (none of the DT files merged upstream ever used these features), switch to panel-bridge driver, removing the need to handle drm_panel codepaths separately and finally switch to drm_bridge_connector, removing requirement for the downstream bridges to create drm_connector on their own. This has been tested on the iMX53 with the DPI panel attached to LDB via LVDS decoder, using all possible usecases (lvds-codec + panel, panel linked directly to LDB node and the display-timings node).
