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).
