Input: alps - report V2 Dualpoint Stick events via the right evdev node
On V2 devices the DualPoint Stick reports bare packets, these should be reported via the "AlpsPS/2 ALPS DualPoint Stick" dev2 evdev node, which also has the INPUT_PROP_POINTING_STICK propbit set. Note that since there is no way to distinguish these packets from an external PS/2 mouse (insofar as these laptops have an external PS/2 port) this means that we will be reporting PS/2 mouse events via this evdev node too, as we've been doing in kernel 3.19 and older. This has been tested on a Dell Latitude D620 and a Dell Latitude E6400, which both have a V2 touchpad + a DualPoint Stick which reports bare packets.
