Mark Yao f767345350 drm/rockchip: vop: add rk3036 vop support
RK3036 registers layout is quite difference with rk3288 layout,
The IC design with different framework, rk3036 vop is VOP LITE,
and rk3288 is VOP FULL.

RK3036 support two overlay plane and one hwc plane, max output
resolution is 1080p. it support IOMMU, and its IOMMU same as
rk3288's.
