[PATCH] gpio: ml_ioh_gpio: Fix output value of ioh_gpio_direction_output()

[Peter Tyser <ptyser@xes-inc.com>]

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.

This is untested - just noticed it while working on an unrelated change.  An
ack or tested-by from someone with real hardware would be appreciated.
