gpio: arizona: Fix runtime PM leak in arizona_gpio_direction_out()
Switching a persistent GPIO line from input to output acquires a
runtime PM reference on the parent device, but if the subsequent
regmap_update_bits() fails the reference is never dropped and no later
direction_in() can balance it since the direction was never changed.
Drop the reference on the update failure path.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
