The GPIO get callback is expected to return 0 or 1 (or a negative error
code). Ensure that the value returned by qca807x_gpio_get() is
normalized to the [0, 1] range.

Fixes: 86ef402d805d ("gpiolib: sanitize the return value of gpio_chip::get()")

v2: add correct netdev tree prefix and "fixes" tag.
