Update gpio.txt based on recent discussions regarding interaction with the
pinctrl subsystem.

Previously, gpio_request() was described as explicitly not performing any
required mux setup operations etc.

Now, gpio_request() is explicitly as explicitly performing any required mux
setup operations where possible. In the case it isn't, platform code is
required to have set up any required muxing or other configuration prior to
gpio_request() being called, in order to maintain the same semantics.

This is achieved by gpiolib drivers calling e.g. pinctrl_request_gpio() in
their .request() operation.

Grant can you take this one? I'd prefer for you to have a look at
it as well.

I've taken this one, but left the 2nd for Olof.

Grant, did you take V2 of this patch? I assume not since you replied to V1.

For reference, that's:

Thanks.
