From: Chaoyi Chen <chaoyi.chen@rock-chips.com>
On the RK3506 platform, there is no iommu hardware. And even on
platform that have iommu hardware, it should be possible to use
VOP without enabling iommu. In this case, a contiguous memory
space like CMA should be used.
So this patch removes the dependency on ROCKCHIP_IOMMU.
