[MIPS] au1000: Fix gpio direction
When setting the direction of one GPIO pin we have to keep the state of the other pins, hence use binary OR. Also gpio_direction_output() wants to set an initial value, so add that too. This fixes a problem with the USB power switch on mtx-1 boards. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
