This patch adds basic support for the Logitech G920 wheel when in HID
mode. This wheel 'speaks' the HID++ protocol, and therefor is driven
with hid-logitech-hidpp.
At this stage the driver only shows that it can communicate with the
wheel by outputting the name discovered over HID++.
The normal HID functions work to give input functionality using
joystick/event interface.
Note: in 'hidpp_probe()' we have to start the hardware to get packets
flowing, the same might apply in future for other devices which don't
use the unifying protocol.

Also because of the above changes we don't need special handling
