spi: gpio: clarify gpio chipselect language

Commit 7431798490 (of_spi: add generic binding support to specify cs gpio)

however, is an internal implementation detail of the Linux SPI subsystem, and
should not be mentioned in the device tree binding documentation. Mention the
previously defined cs-gpios master node property instead.
