The DSS controller on TI's AM625 SoC is an update from that on TI's
AM65X SoC. The former has an additional OLDI TX on its first video port
(VP0) that helps output cloned video or WUXGA (1920x1200@60fps)
resolution video output over a dual-link mode to reduce the required
OLDI clock output.
Add the new controller's compatible and a port property for the 2nd OLDI
TX (OLDI TX 1).
