Input: synaptics - add Lenovo 80 series ids to SMBus
commit ad8fb554f04e38f155c9bc34bbf521fc592ceee7 upstream.
This time, Lenovo decided to go with different pieces in its latest
series of Thinkpads.
For those we have been able to test:
- the T480 is using Synaptics with an IBM trackpoint
-> it behaves properly with or without intertouch, there is no point
not using RMI4
- the X1 Carbon 6th gen is using Synaptics with an IBM trackpoint
-> the touchpad doesn't behave properly under PS/2 so we have to
switch it to RMI4 if we do not want to have disappointed users
- the X280 is using Synaptics with an ALPS trackpoint
-> the recent fixes in the trackpoint handling fixed it so upstream
now works fine with or without RMI4, and there is no point not
using RMI4
- the T480s is using an Elan touchpad, so that's a different story
