[v3,0/21] drm/bridge: support chained bridges + panel updates

Message

This patch-set aims to make connector creation optional
and prepare the bridge drivers for use in a chained setup.

The objective is that all bridge drivers shall support a chained setup
connector creation is moved to the display drivers.
This is just one step on this path.

Third iteration of this patchset covers several drivers,
and a few panel adjustments.

The general approach for the bridge drivers:
- Introduce drm_panel_brigde
- Introduce bridge operations
- Make connector creation optional

v3:
  - Rebase on top of drm-misc-next
  - Address kbuild test robot feedback
 
v2:
  - Updated bus_flags for boe,hv070wsa-100
  - Collected r-b, but did not apply patches yet
  - On the panel side the panel-simple driver gained a default
    connector type for all the dumb panels that do not
    include so in their description.
    With this change panels always provide a connector type,
    and we have the potential to drop most uses of
    devm_drm_panel_bridge_add_typed().
  - Added conversion of a few more bridge drivers

Patches can build but no run-time testing.
So both test and review feedback appreciated!
