[PATCH] platform/chrome: chromeos_acpi: use official HID GOOG0016

[Tzung-Bi Shih <tzungbi@kernel.org>]

Use official HID GOOG0016 for ChromeOS ACPI (see [1]).

AFAIK, there has no ChromeOS devices using the driver yet.  Instead, they
still stick to some downstream implementation.  IOW, I guess we are safe
to just replace the PNP ID.
