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.

Linux bindings have been introduced in the code (removing the U-Boot
specific ones) without documentation update. Compatible string has
changed, as well as the four GPIO properties. Reflect this by updating
the soft-spi.txt documentation.

Add a new implementation of soft_spi that uses device tree to specify the
GPIOs. This will replace soft_spi_legacy for boards which use driver model.
