Input: synaptics - disable Intertouch for Lenovo T14 and P14s AMD G1

Since intertouch was enabled for the T14 and P14s AMD G1 laptops there
have been a number of reports of touchpads not working well.

Debugging this with Synaptics they noted that intertouch should not be
enabled as SMBUS host notify is not available on these laptops.

Reverting the previous commit (e4ce4d3a939d97bea045eafa13ad1195695f91ce)
to restore functionality back to what it was.

Note - we are working with Synaptics to see if there is a better
solution, but nothing is confirmed as yet.
