Register values in DT are frowned upon.

This sounds similar to the bus-type property defined in
Documentation/devicetree/bindings/media/video-interfaces.txt (which is
getting converted to YAML, Rob has posted a patch series, I expect it to
land in v5.13). I think it would make sense to extend bus-type to
support DSI, and use that property.
