The commits mentioned below adapt the GPIO API to allow more information
to be passed directly through devm_get_gpiod_from_child() in the first
instance.  This facilitates the removal of subsequent calls, such as
gpiod_direction_output().  This patch firstly moves to utilise the new
API and secondly removes the now superfluous call do set the direction.

Fixes: a264d10ff45c ("gpiolib: Convert fwnode_get_named_gpiod() to configure GPIO")
Fixes: b2987d7438e0 ("gpio: Pass GPIO label down to gpiod_request")
Fixes: 4b0947974e59 ("gpio: Rename devm_get_gpiod_from_child()")
