DSI-attached devices could respond to more than one virtual channel number, thus their bindings are supposed to constrain the 'reg' property to match hardware. Add missing 'reg' constrain for DSI-attached display panels, based on DTS sources in Linux kernel (assume all devices take only one channel number).
