zephyr/machine_pin: Retry configuring gpio with just GPIO_OUTPUT.

Browse source 
Some targets like frdm_k64f don't support GPIO_OUTPUT|GPIO_INPUT, so just
use GPIO_OUTPUT in those cases (it seems they still support reading the
current output state even when configured only as GPIO_OUTPUT, unlike other
targets which require both settings).
