drm/rockchip: rewrite IOMMU support code

This patch is learn from Marek Szyprowski's patch:
(drm/exynos: rewrite IOMMU support code)

The patch replaces usage of ARM-specific IOMMU/DMA-mapping related calls
with new generic code for managing DMA-IOMMU integration layer. It also
removes all the hacks, which were needed to configure common DMA/IO address
space on the virtual rockchip-drm device.
