gpiolib: Convert fwnode_get_named_gpiod() to configure GPIO

Browse Source 
Make fwnode_get_named_gpiod() consistent with the rest of
gpiod_get() like API, i.e. configure GPIO pin immediately after
request.

Besides obvious clean up it will help to configure pins based
on firmware provided resources.
