Input: xpad - fix rumble on Xbox One controllers with 2015 firmware

BugLink: https://bugs.launchpad.net/bugs/1810967

[ Upstream commit 540c2608 ]

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.
