gpio/ml_ioh_gpio: Fix output value of ioh_gpio_direction_output()
The ioh_gpio_direction_output() function was missing a write to set the desired output value. The function would properly set the GPIO direction, but not the output value. The value would have to manually be set with a follow up call to ioh_gpio_set(). Add the missing write so that ioh_gpio_direction_output() sets both the GPIO direction and value.
