[PATCH v5 1/5] dt-bindings: display: panel: add Truly NT36850 WQHD panel

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

Describe the Truly 5.7" WQHD dual-DSI command mode panel based on the
Novatek NT36850, used on the display cards for the Qualcomm SDM845 and
SM8150 HDKs.

The model name of the panel is not known. Neither the vendor kernel nor
the HDK documentation mention it, and the panel block cannot be taken
apart completely to check the label. So the compatible is built from
the vendor, resolution, refresh rate and the controller name.
