drm/bridge: imx: Add i.MX93 MIPI DSI support

Freescale i.MX93 SoC embeds a Synopsys Designware MIPI DSI host
controller and a Synopsys Designware MIPI DPHY.  Some configurations
and extensions to them are controlled by i.MX93 media blk-ctrl.

Add a DRM bridge for i.MX93 MIPI DSI by using existing DW MIPI DSI
bridge helpers and implementing i.MX93 MIPI DSI specific extensions.
