This patch adds the needed display info for rk3036 SOCs.

The rk3036 support two overlay plane and one hwc plane,
it supports IOMMU, and its IOMMU same as rk3288's.
Meanwhile, add the inno hdmi for HDMI display.

I've split this into 3 patches (vop, hdmi, kylin enablement) and applied 
this to my dts32 branch.
