Input: synaptics - whitelist Lenovo T580 SMBus intertouch

commit 1976d7d200c5a32e72293a2ada36b7b7c9d6dd6e upstream.

Adds the Lenovo T580 to the SMBus intertouch list for Synaptics
touchpads. I've tested with this for a week now, and it seems a great
improvement. It's also nice to have the complaint gone from dmesg.
