[Freedreno] [PATCH 1/5] dt-bindings: display/msm: Add reg bus interconnect

[Konrad Dybcio]

Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's
another path that needs to be handled to ensure MDSS functions properly,
namely the "reg bus", a.k.a the CPU-MDSS interconnect.

Gating that path may have a variety of effects.. from none to otherwise
inexplicable DSI timeouts..

Describe it in bindings to allow for use in device trees.
