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).

that is in turn using the NT35510 panel driver. The compatible

string determines how the NT35510 panel driver shall be configured
|
|
to work with the indicated panel. The novatek,nt35510 compatible shall
|
|
always be provided as a fallback.
