This patch adds support for trackpoint on elantech driver for v3 models

Changes since v1:
* New patch now with reference to 3.14rc1
* Added etd->trackpoint_present to indicate presence of trackpoint (based
  on MSB of etd->capabilities[0])
* trackpoint will only be registered now when MSB of etd->capabilities[0] is
  set; got confirmation that this is the indicator of trackpoint
* Added input_unregister_device/input_free_device in elantech_disconnect()
* Fixed a bug in cleaning up when elantech_init fails
* Rename commit to be more specific (now also applicable to future elantech
  v3 models with trackpoint)
* input device name 'TPPS/2 IBM TrackPoint' changed to
  'Elantech PS/2 TrackPoint', this patch is not ibm/lenovo specific!
* dev2 renamed to tp_dev to indicate that this is the trackpoint device
* etd->phys renamed to etd->tp_phys
* Added Lenovo 530 and Fujitsu H730 to the laptop list because those are now
  also known.
* Added psmouse_reset at the end of elantech_init when it fails
* Added warning when trackpoint packets are received with no trackpoint detected
