Changes to the existing (txt) schema: - Added optional "vbif_nrt_phys" region used by msm8996 - Made "bus" and "vsync" clocks optional (they are not used by some platforms) - Added optional resets property referencing MDSS reset - Defined child nodes pointing to corresponding reference schema. - Dropped the "lut" clock. It was added to the schema by mistake (it is a part of mdp4 schema, not the mdss).
