We don't need it for the first half (gpio_set_value, gpio_direction_input, ...),
which could just be unconditional wrappers around the gpiod versions.
Removing that #ifdef would require always including linux/gpio/consumer.h
here, so we'd no longer get a build failure when a driver uses gpiod_*
without including that directly (when GPIOLIB is disabled).

I actually had a patch in my series to do this, but dropped that because
the second half (gpio_request/gpio_free/...) does need the #ifdef
