gpio: tps68470: Make tps68470_gpio_output() always set the initial value
[ Upstream commit 5a7adc6c1069ce31ef4f606ae9c05592c80a6ab5 ]
Make tps68470_gpio_output() call tps68470_gpio_set() for output-only pins
too, so that the initial value passed to gpiod_direction_output() is
honored for these pins too.
