From: Fabio Estevam festevam@denx.de
According to Documentation/devicetree/bindings/spi/spi-gpio.yaml from Linux, the recommended spio-gpio properties are:
sck-gpios, miso-gpios and mosi-gpios.
gpio-sck, gpio-mosi and gpio-miso are considered deprecated.
Update the bindings to suggest the recommeded properties.
