[SRU] TrackPoint: middle button doesn't work on TrackPoint-compatible device.

[AaronMa]

Lenovo introduced 4 new TrackPoint compatible sticks those only support the minimum commands described in the spec, which has been used in the current Windows driver.

Legacy TrackPoint: 0101 – 0E01

ALPS: 0102 – FF02

ELAN:0103 – FF03

NXP: 0104 – FF04

TrackPoint (ID: 01/02) report 0 button when reading the EXT_BUTTON command.

Setting middle button enabled to make it work.

    Input: trackpoint - force 3 buttons if 0 button is reported

    Lenovo introduced trackpoint compatible sticks with minimum PS/2 commands.
    They supposed to reply with 0x02, 0x03, or 0x04 in response to the
    "Read Extended ID" command, so we would know not to try certain extended
    commands. Unfortunately even some trackpoints reporting the original IBM
    version (0x01 firmware 0x0e) now respond with incorrect data to the "Get
    Extended Buttons" command:

     thinkpad_acpi: ThinkPad BIOS R0DET87W (1.87 ), EC unknown
     thinkpad_acpi: Lenovo ThinkPad E470, model 20H1004SGE

     psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 0/0

    Since there are no trackpoints without buttons, let's assume the trackpoint
    has 3 buttons when we get 0 response to the extended buttons query.

SRU justification:
==============
[Impact]
Middle button on some TrackPoints with ThinkPad can't work on Ubuntu
16.04.
Lenovo introduced 4 new TrackPoint compatible sticks those only support
minimum commands, Sticks with ID 01/02 reported the external button 0,
TrackPoint always have 3 buttons.

[Fix]
Set 3 buttons when 0 button is reported via PS/2 commands.

[Test Case]
Tested on Finn and E470, middle button works with this patch.

[Regression Potential]
No regression is expected.

This patch had been send to stable kernel, so Bionic should have it
with stable updates.
