From: Randy Dunlap <rdunlap@infradead.org>

DRM_RCAR_CMM depends on DRM_RCAR_DU. Since the following Kconfig
symbols do not depend on DRM_RCAR_DU, the menu presentation is
broken for these and following non-R-Car Kconfig symbols.

Is it safe/appropriate to make all of these symbols depend on
DRM_RCAR_DU?  It make the kconfig menu presentation much cleaner.
