Documentation: gpio: Explain that <function>-gpio is also supported
The GPIO documentation mentions that GPIOs are mapped by defining a <function>-gpios property in the consumer device's node but a -gpio sufix is also supported after commit: dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names") Update the documentation to match the implementation.
