mb/google/guybrush: update ACPI HID/CID for Synaptics touchpad
The currently assigned ACPI HID 'PNP0C50' is not a valid per Windows
WHQL validation tests. To ensure compatibility with both Windows and
Linux, set the HID to 'SYNA0000' and CID to 'ACPI0C50' as previously
done for other boards (eg, google/lulu).
TEST=boot ChromeOS, Linux 5.1x, Windows 10 on dewatt, verify all
touchpad functions work correctly.
