The panel is a SPI slave - which is not too obvious from the old
binding.

The new DT Schema includes spi/spi-slave.yaml to give the binding
proper access to the spi slave properties.

That would not be possible with panel-simple binding as no further
properties are allowed with the panel-simple binding.

I hope this explains why there is a dedicated binding for this panel.
