[PATCH v3] drm: rcar: unbreak the R-Car menu items

[Randy Dunlap]

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 the following R-Car Kconfig symbols.

Use an if/endif block to make all of these symbols depend on
DRM_RCAR_DU (and remove the separate "depends on DRM_RCAR_DU").
This makes the kconfig menu presentation much cleaner.

v2: use an if/endif block for the dependencies (thanks, Geert)
v3: still applicable -- update/rebase

Applies after today's earlier patch to fix undefined reference
build errors for R-Car (probably won't matter).

I did this patch one year ago and then forgot about it somehow.
Rediscovered & updated it today.
