mb/google/volteer: update ACPI HID/CID for Synaptics touchpads

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 Linux 5.1x, Windows 10 on lindar, verify all touchpad
functions work correctly.
