drm/bridge: Add ICN6211 MIPI-DSI/RGB bridge
This is v2 series for supporting Chipone ICN6211 DSI/RGB bridge,
here is the previous version set[1]
The overlay patch, has Bananapi panel which would depends on,
previous MIPI DSI fixes series[2] to make the panel works.
Changes for v2:
- use panel_or_bridge for finding panel and bridge
- add panel overlay dts patch for port based panel enablement
- update the bridge sequence dynamically, by getting mode
timings from panel-simple
- correct the brinding compatible
- add more information in binding example
- replace the bridge detach with proper ops
- add bridge overlay dts patch for port based panel enablement
[2] https://patchwork.freedesktop.org/series/60847/
[1] https://patchwork.freedesktop.org/series/58060/
Any inputs?
Jagan.

Right now the driver is finding the panel using of_drm_find_panel,
replace the same with drm_of_find_panel_or_bridge which would help
to find the panel or bridge on the same call if bridge support added
in future.
Added NULL in bridge argument, same will replace with bridge parameter
once bridge supported.
