mpc85xx: make gpio_direction_output respect value
Users of familiar with the Linux gpiolib API expect that value parameter
to gpio_direction_output reflects the initial state of the output pin.
gpio_direction_output was always driving the output low, now it drives
it high or low according to the value provided.
