Andrey Smirnov 73c5b254c3 HID: microsoft: Add rumble support for Xbox One S controller 
Add HID quirk driver for Xbox One S controller over bluetooth.

This driver only adds support for rumble. Standard controller
functionality is exposed by default HID driver.

[jkosina@suse.cz: straightforward rebase on more recent driver code]
