spi/panel: dt-bindings: drop CPHA and CPOL from common properties
The spi-cpha and spi-cpol properties are device specific and should be
accepted only if device really needs them. Drop them from common
spi-peripheral-props.yaml schema, mention in few panel drivers which use
them and include instead in the SPI controller bindings. The controller
bindings will provide CPHA/CPOL type validation and one place for
description. Each device schema must list the properties if they are
applicable.
