I can't see any other platform using this.
No one uses compatible "cdns,mhdp8546" and only K3 devices uses the
wrapper compatible "ti,j721e-mhdp8546"
Let me post next RFC version with legacy !DRM_BRIDGE_ATTACH_NO_CONNECTOR
dropped.

And the mentioned series only touches mailbox access function to move
then to a common helper file. (So independent change)
