gpio: merrifield: Fix build err without CONFIG_ACPI

When building CONFIG_ACPI is not set
gcc warn this:

drivers/gpio/gpio-merrifield.c: In function mrfld_gpio_get_pinctrl_dev_name:
drivers/gpio/gpio-merrifield.c:388:19: error: dereferencing pointer to incomplete type struct acpi_device
   put_device(&adev->dev);
                   ^~
