When the R-Car MIPI DSI driver was added, it was a standalone encoder driver without any dependency to or from the R-Car DU driver. Commit 957fe62d7d15 ("drm: rcar-du: Fix DSI enable & disable sequence") then added a direct call from the DU driver to the MIPI DSI driver, without updating Kconfig to take the new dependency into account. Fix it the same way that the LVDS encoder is handled.
