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).

Backlight to use for the panel. If this property is set on panels

that have DSI-based backlight control (LSL080AL03 and LTL101AT01),
|

it overrides the DSI-based backlight.
