[Phidias Chiang]

BugLink:  http://bugs.launchpad.net/bugs/1515503

[Impact]

Some RMI4 touchpad doesn't work properly even the probing returns no error.
Further investigation shows the interrupt doesn't increase at all.
There's already a public bug and the patch is already upstreamed:

    HID: rmi: Set F01 interrupt enable register when not set

Other commits in this patch set are for dependencies

Note:
So far the platform we encounter with this issue use GPIO interrupt,
so it also needs 3.19.0-32 or Wily kernel to work too.

[Test]

1. Boot with v4.3-rc1 -> pass
2. Boot with patched Vivid kernel -> pass
3. Boot with patched Wily kernel -> pass
