gpio: Pass GPIO label down to gpiod_request
Currently all users of fwnode_get_named_gpiod() have no way to
specify a label for the GPIO. So GPIOs listed in debugfs are shown
with label "?". With this change a proper label is used.
Also adjust all users so they can pass a label, properly retrieved
from device tree properties.
