HID: Add support for Logitech Speed Force Wireless gaming wheel

Browse Source 
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.
