dt-bindings: display: bridge: waveshare,dsi2dpi: Document 1..4 DSI lane support

Browse Source 
Describe 1..4 DSI lanes as supported. Internally, this bridge is
an ChipOne ICN6211 which loads its register configuration from a
dedicated storage and its I2C does not seem to be accessible. The
ICN6211 supports up to 4 DSI lanes, so this is a hard limit for
this bridge. The lane configuration is preconfigured in the bridge
for each of the WaveShare panels.
