Peter Gundermann fdc6807fcd HID: add support for Logitech G27 wheel 
Gere's a small patch to add support for the Logitech G27 wheel, since
the prior patch only added FF support for the Driving Force Pro and G25.
The patch contains the changes from the G25 and DFP, too.

I tested the changes with wine/LFS and got full support for all axes and
buttons.
