[patch] HID: use hid-plff driver for GreenAsia 0e8f:0003 devices

[Anssi Hannula <anssi.hannula@gmail.com>]

Add 0e8f:0003 into the list of devices supported by the hid-plff
force feedback driver. These devices identify themselves as
"GreenAsia Inc.    USB Joystick     " and can be either adapters or
actual game controllers. The testing was done with a Köng Gaming
gamepad.
