google/clapper: fix up devicetree
When clapper was upstreamed, the devicetree was pulled from the wrong firmware branch, leading to some incorrect settings and touchpad, touchscreen, and audio not working. Correct devicetree settings using Chromium branch firmware-clapper-5216.199.B Test: build/boot google/clapper, verify touchpad/touchscreen/audio functional under Linux (GalliumOS 3.0/kernel 4.16.18).
