Fix this by moving the mdp component nodes up a level such that they are siblings of mdp and all other SoC subsystems. This also simplifies the device tree. Although it fixes iommu assignment issue, it also break compatibility with old device tree. So, the patch in driver is needed to iterate over sibling mdp device nodes, not child ones, to keep driver work properly.
