HID: alps: allow incoming reports when only the trackstick is openedfor-4.20/upstream-fixes
If userspace only reads the trackstick node, and no one is listening to
the touchpad nor the hidraw node then, the device is not powered on.
Add open/close callbacks to allow users to disable the touchpad in Gnome
while keeping the trackstick active.
