mb/google/parrot: override SMBus subsystem ID
Necessary to allow coolstar's Windows touchpad driver for this board,
since the touchpad is attached to the SMBus. The VID/DID combo used is
not registered/doesn't conflict with any currently in use, and would
be difficult to change at this point since the Windows drivers have
already been signed.
TEST=build/boot Win11, Linux on butterfly/lumpy/parrot, verify
touchpad driver works properly.
