[PATCH 1/2] dt-bindings: display: panel: Fork Waveshare panels into separate document

Move the Waveshare panels description into separate document, so they
can be properly described with compatible = "waveshare,...", "panel-dpi"
and attached to "waveshare,dsi2dpi" bridge.

While these panels are described as DPI panels, they are generally part
of a larger unit in non-removable metal casing, so the actual internal
configuration is not known. It is likely that internally, those panels
are LVDS panels, connected to ICN6211 DSI-to-DPI bridge and then another
unknown DPI-to-LVDS bridge.
