Patch documented only Single link LVDS as it only supported by driver.
Single link LVDS with Channel A configuration is common across all 3
variant chips. I have SN65DSI84 with Single link LVDS which is routed
in Channel A. Idea is to go with Single link and add double link later
and document the same.
