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.

It may simplify the DT, but it also breaks compatibility with old DT. 
Not sure if that's a problem on Mediatek platforms, but please be 
explicit here that you are breaking compatibility and why that is okay.

I will add the following description for more information.
"
Although it fixes iommu assignment issue, it also break compatibility
with old device tree, so driver patch[1] is needed to iterate over
sibling mdp device nodes, not child ones, to keep driver work properly.
In mtk_mdp_probe()
Old: for_each_child_of_node(dev->of_node, node)
New: for_each_child_of_node(dev->of_node->parent, node)

This patch is provided by Daniel, so I keep he is the author.
I just split his patch into two parts. One is dts only, and the other is
for driver. I also provide another patch to modify dts bindings
according to this patch.
