After looking closer at DSS last few days, the OLDI is unfortunately
different on AM62x.
Even though DPI interface works fine, OLDI TX integration needs a
separate compatible.
I suggest sending a patch introducing ti,am625-dss compatible.
I will need to drop the entire series - if we can get the compatible
integrated to master, i can pick the dts updates in the rc1 after.
