    broadwell: Add handler for finding ACPI path for GPIO
    
    Add a handler for the Intel Broadwell SOC to return the ACPI path for
    GPIOs.  Since all GPIOs are handled by the same controller they all
    have the same ACPI path and this is a simple handler that just returns
    a pointer to the GPIO device that is defined in the DSDT.
