HID: force feedback driver for GreenAsia 0x12 PID 

I have implemented Force Feedback driver for another "GreeAsia" based device
(0e8f:0012 "GreenAsia Inc. USB Joystick"). The functionality was tested with
MANTA Warior MM816 and SpeedLink Strike2 SL-6635 and fftest software -
everything seems to work right.
