The spi-3wire property is device specific and should be accepted only if
device really needs them. Drop it from common spi-peripheral-props.yaml
schema, mention in few panel drivers which use it and include instead in
the SPI controller bindings. The controller bindings will provide
spi-3wire type validation and one place for description. Each device
schema must list the property if it is applicable.
The Samsung S6E63M0 panel uses also spi-cpha/cpol properties on at least
one board (ste-ux500-samsung-janice/dts), so add also these to the
panel's bindings.
