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.
