From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx>
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
