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
