drm/panel: Add support for ARM Versatile panels
The ARM reference designs "Versatile AB" and "Versatile PB"
contain panel connectors with autodetection of the connected
panel type. This adds a small driver utilizing the MFD syscon
look-up to read the autodetection register and set up the
corresponding panel appropriately.
In the source file there is a bit of elaboration of the
panel types and interfaces on these boards.
This was tested with the PL111 DRM driver on the ARM Versatile
AB with the IB2 daughterboard.
