[PATCH 3/3] UBUNTU: SAUCE: Input: synaptics - add Intertouch support on X1 Carbon 6th and X280

[Aaron Ma]

BugLink: http://bugs.launchpad.net/bugs/1723986

Link: https://patchwork.kernel.org/patch/10008513/

Synaptics devices reported it has Intertouch support,
and it fails via PS/2 as following logs:

psmouse serio2: Failed to reset mouse on synaptics-pt/serio0
psmouse serio2: Failed to enable mouse on synaptics-pt/serio0

Set these new devices to use SMBus to fix this issue,
then they report SMBus version 3 is using,
patch: https://patchwork.kernel.org/patch/9989547/ enabled SMBus ver 3 and
makes synaptics devices work fine on SMBus mode.
