[PATCH 1/3] drm: rcar-du: DRM_RCAR_DW_HDMI should depend on ARCH_RENESAS

[Geert Uytterhoeven]

The Renesas R-Car Gen3 and RZ/G2 internal HDMI encoder is only present
on Renesas R-Car Gen3 and RZ/G2 SoCs.  Hence add a dependency on
ARCH_RENESAS, to prevent asking the user about this driver when
configuring a kernel without Renesas SoC support.
