[PATCH] pch_gpio: Fix output value of pch_gpio_direction_output()

[Tomoya MORINAGA]

The pch_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 pch_gpio_set().

Add the missing write so that pch_gpio_direction_output() sets both the
GPIO direction and value.
