pinctrl: armada-37xx: set GPIO output value before setting direction
Changing the direction before updating the output value in the
OUTPUT_VAL register may result in a glitch on the output line
if the previous value in the OUTPUT_VAL register is different
from the one we want to set.
In order to avoid that, update the output value before changing
the direction.
