lynxpoint: Expose ACPI Device for LP GPIO controller

In order to probe the gpio-lynxpoint kernel driver the
    LP GPIO controller needs to be exposed as a specific
    ACPI device.

This also allows the resources to be exposed to the OS via
    this device instead of the catch-all LPC device.

Ensure the driver loads at boot:
    gpiochip_find_base: found new base at 162
    gpiochip_add: registered GPIOs 162 to 255 on device: INT33C7:00

Also ensure the driver is visible in sysfs:
    $ cat /sys/devices/platform/INT33C7:00/gpio/gpiochip162/label
    INT33C7:00
