gpiolib: implement gpiod_set_value
Linux gpiod_set_value is silent if the GPIO descriptor is NULL, but
barebox warns about it. Also having gpio_set_value not respect active
low/high, while Linux gpiod_set_value respects it is error-prone.
Add a new gpiod_set_value function that covers this. gpio == -ENOENT is
taken as the dummy value for optional GPIOs.
