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.
