skylake: Add handler for finding ACPI path for GPIO
Add a handler for the Intel Skylake 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.
