[PATCH 3/3] drm: rcar-du: DRM_RCAR_MIPI_DSI should depend on ARCH_RENESAS

[Geert Uytterhoeven]

The Renesas R-Car Display Unit embedded MIPI DSI encoder is only present
on Renesas R-Car V3U SoCs.  Hence add a dependency on ARCH_RENESAS, to
prevent asking the user about this driver when configuring a kernel
without Renesas SoC support.
