arm64: dts: ti: k3-j721e-main: Add DSI and DPHY-TX

TI's J721E SoC supports a DPI to DSI video signal conversion bridge on
it's platform bus. The IP is from Cadence, and it has a custom TI
wrapper around it to facilitate integration.

This IP takes the DPI video signals from DSS and alongwith the DPHY IP,
it transmits DSI video signals out of the SoC.

Add support for DSI bridge and the DPHY-TX.
