Existing MDP5 devices have slightly different bindings. The main
register region is called `mdp_phys' instead of `mdp'. Also vbif
register regions are a part of the parent, MDSS device. Add support for
handling this binding differences.

The commit 6874f48bb8b0 ("drm/msm: make mdp5/dpu devices master
components") changed the MDP5 driver to look for the interconnect paths
in the MDSS device rather than in the MDP5 device itself. This was left
unnoticed since on my testing devices the interconnects probably didn't
reach the sync state.
Rather than just using the MDP5 device for ICC path lookups for the MDP5
devices, introduce an additional helper to check both MDP5/DPU and MDSS
nodes. This will be helpful for the MDP5->DPU conversion, since the
driver will have to check both nodes.
