drm/bridge: waveshare-dsi: support DSI LCD kits with LVDS panels

Browse Source 
Several Waveshare DSI LCD kits use LVDS panels and the ICN6202 DSI2LVDS
bridge. Support that setup by handling waveshare,dsi2lvds compatible.
The only difference with the existing waveshare,dsi2dpi is the bridge's
output type (LVDS vs DPI).
