[PATCH] drm/rockchip: DRM_ROCKCHIP should depend on ARCH_ROCKCHIP

[Geert Uytterhoeven]

Rockchip display hardware is only available on Rockchip SoCs.  Hence add
a dependency on ARCH_ROCKCHIP, to prevent asking the user about this
driver when configuring a kernel without Rockchip platform support.

Before, this dependency was implicit through a hard dependency on
ROCKCHIP_IOMMU.

Fixes: 0244539f9a4f3b56 ("drm/rockchip: Drop ROCKCHIP_IOMMU depend for DRM_ROCKCHIP")
