SPI-attached devices could have more than one chip-select, thus their bindings are supposed to constrain the 'reg' property to match hardware. Add missing 'reg' constrain for SPI-attached display panels.

This is a driver for 320x240 TFT panels, accepting a variety of input
|
|
streams that get adapted and scaled to the panel. The panel output has
|
|
960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and
|
|
VCOMH outputs.
