HID: lenovo: Add support for IBM/Lenovo Scrollpoint mice 

[ Upstream commit a230cd52b8 ]

The IBM/Lenovo Scrollpoint mice feature a trackpoint-like stick instead of a
scrolling wheel capable of 2-D (vertical+horizontal) scrolling.  hid-generic
does only expose 1-D (vertical) scrolling functionality for these mice.  This
patch adds support for horizontal scrolling for the IBM/Lenovo Scrollpoint mice
to hid-lenovo.
