Use the FORCE_MULTI_INPUT class and quirk added in
commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk
for some devices")
to enable event reporting from both the trackpad and the
trackpoint/buttons in the Lenovo X1 Tab gen2.
Signed-off-by: David Edmondson <david.edmondson@xxxxxxxxxx>

It seems likely that some other devices should be treated similarly
(X1 Tab gen3, for example), but I don't have them available to test.
