HID: fix Logitech WingMan Formula GP joined axes
The Logitech WingMan Formula GP by default presents a combined accelerate/brake axis, so this patch assigns it to hid-logitech in order to benefit from the axis-splitting logic in lg4ff. There is also a fixed report descriptor for the resulting report. Signed-off-by: Jarrad Whitaker <jarrad.whitaker@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
