spi: pl022: Specify 'num-cs' property as required in devicetree binding
Since commit 39a6ac11df65 ("spi/pl022: Devicetree support w/o platform data")
the 'num-cs' parameter cannot be passed through platform data when probing
with devicetree. Instead, it's a required devicetree property.
Fix the binding documentation so the property is properly specified.
