drm/bridge: cdns-dsi: Add support for J721E wrapper
Add support for wrapper settings for DSI bridge on j721e. Also enable
DPI0
--------------- -----------------------
| -------| |------- |
| DSS | DPI2 |----->| DPI0 | DSI Wrapper |
| -------| |------- |
--------------- -----------------------
As shown above DPI2 output of DSS is connected to DPI0 input of DSI
Wrapper, DSI wrapper gives control wheather to enable/disable DPI0
input. In j721e above is the only configuration supported
