dt-bindings: display: ti,am65x-dss: Add am625 dss compatible 

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
that helps output cloned video or WUXGA (1920x1200@60fps) resolution
video output over a dual-link mode to reduce the required OLDI clock
output.

The second video port is same from AM65x DSS and it outputs DPI video
data. It can support 2K resolutions @ 60fps, independently.

Add the new controller's compatible and update descriptions.

The AM65x TI Keystone Display SubSystem with two output ports and
two video planes. The first video port supports OLDI and the second
supports DPI format. The fist plane is full video plane with all
features and the second is a "lite plane" without scaling support.
The AM625 and AM65x TI Keystone Display SubSystem with two output
ports and two video planes. In AM65x DSS, the first video port
supports 1 OLDI TX and in AM625 DSS, the first video port output is
internally routed to 2 OLDI TXes. The second video port supports DPI
format. The first plane is full video plane with all features and the
second is a "lite plane" without scaling support.
