ec/quanta/it8518: add missing HID to SIO device 

The ACPI spec requires devices with children to have an HID,
and Windows enforces this strictly. Without the SIO device
having an HID, Windows will not detect the attached PS2 keyboard
and trackpad.  Therefore, add the proper HID.

TEST: boot Windows on google/stout, observe PS2 keyboard and
trackpad detected and functional.
