spi: pl022: Specify 'num-cs' property as required in devicetree binding
commit ea6055c46eda1e19e02209814955e13f334bbe1b upstream. 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.

The gpios will be referred to as reg = <index> in the SPI child nodes.
If unspecified, a single SPI device without a chip select can be used.
