[PATCH 2/6] dt-bindings: serial: 8250_omap: Add compatible for J721E UART controller

[Nishanth Menon]

J721e uses a UART controller that is compatible with AM654 UART.
Introduce a specific compatible to help handle the differences if
necessary.

NOTE:
 - If Greg is ok, we can pick up the uart compatibility via the k3 tree,
   else, I can spawn it off the series into it's own patch, but it
   seemed better in a logical order.
