Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there are
other connection paths:
- a path that connects rotator block to the DDR.
- a path that needs to be handled to ensure MDSS register access
  functions properly, namely the "reg bus", a.k.a the CPU-MDSS CFG
  interconnect.

Describe these paths bindings to allow using them in device trees and in
the driver
