The following patch adds support for the Logitech Speed Force Wireless gaming
wheel. Originally designed for the WII console. Details on the protocol:

http://wiibrew.org/wiki/Logitech_USB_steering_wheel

This patch relies on previous patch:
"Don't Send Feature Reports on Interrupt Endpoint"

Logitech as produce a very similar wheel for the PS2/PS3, it is expected that
this patch could also support the PS2/PS3 wheel if the USB ID's are added and
(if required) the HID descriptor is modified.

Implements a new USB-HID for Force Feedback based on the normal
Logitech Force Feedback code and FF-Memless.

Currently only supports the FF_CONSTANT effect although the joystick
appears to support additional non-standard ones.

kbuild.h forces include of autoconf.h on the
commandline using -include - so we do not need to
include the file explicit.
