mxs_gpio: fix the handling in gpio_direction_output()
Setting the direction and an output value should be done by
1) set the desired output value,
2) switch to output.
If this is done in the inverse order, there can be a glitch on
the GPIO line.
This patch fixes this by using the order as described above.
