gpio: altera-a10sr: Set proper output level for direction_output
commit 2095a45e345e669ea77a9b34bdd7de5ceb422f93 upstream.
The altr_a10sr_gpio_direction_output should set proper output level
based on the value argument.
Fixes: 26a48c4cc2f1 ("gpio: altera-a10sr: Add A10 System Resource Chip GPIO support.")
