mb/google/stout: Use board-specific PS2M HID/CID to enable multitouch
Use board-specific ASL for PS2-attached trackpad rather than the EC/SIO
default, so that Windows installs a multitouch-capable driver rather
than the standard PS2 mouse driver.
TEST=build/boot Win11 on google/stout, verify trackpad is multitouch
capable.
