HID: AMD_SFH: Add a DMI quirk entry for Chromebooks

Google Chromebooks use Chrome OS Embedded Controller Sensor Hub instead
of Sensor Hub Fusion and leaves MP2 uninitialized, which disables all
functionalities, even including the registers necessary for feature
detections.

The behavior was observed with Lenovo ThinkPad C13 Yoga.
