drm/panel: simple: Add Waveshare 13.3" panel support

Add WaveShare 13.3inch 1920x1080 DSI Capacitive Touch Display support.

While the panel is described as DPI panel, it is part of a larger unit
in non-removable metal casing, so the actual internal configuration is
not known. The panel is attached to "waveshare,dsi2dpi" bridge via DT.
It is likely that internally, this panel is an LVDS panel, connected to
ICN6211 DSI-to-DPI bridge and then another unknown DPI-to-LVDS bridge.
