Xbox One controllers that shipped with or were upgraded to the 2015
firmware discard the current rumble packets we send. This patch changes
the Xbox One rumble packet to a form that both the newer and older
firmware will accept.

It is based on changes made to support newer Xbox One controllers in
the SteamOS brewmaster-4.1 kernel branch.
