I had considered both options but as I suspected that it would have at
least been compile tested by I wasn't 100% sure of the dependency
within the actually SoC as I don't really know the HW but I am happy
to go that route too.

Also the DRM_RCAR_USE_ options seem a little weird too the
DRM_RCAR_USE_MIPI_DSI vs just using DRM_RCAR_MIPI_DSI, seems like
extra logic just in the Kconfig that provides little, but ultimately
that bit doesn't affect me overall.

Will do a v2
