    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.
