Subject: [PATCH v1 1/2] gpiolib: acpi: make fwnode take precedence in struct gpio_chip

If the driver sets the fwnode in struct gpio_chip, let it take
precedence over the parent's fwnode.

This is a follow up to the commit 9126a738edc1 ("gpiolib: of: make
fwnode take precedence in struct gpio_chip").
