docs: driver-api: gpio: Fix filename mismatch
The filenames were changed a while ago, but board.rst, consumer.rst and intro.rst still refer to the old names. Fix those references to match the Actual names and avoid possible confusion. Signed-off-by: Tom Schwindl <schwindl@posteo.de> Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>
