Input: synaptics - add PNP ID for ThinkPad P50 to SMBus

commit 9df39bedbf292680655c6a947c77d6562c693d4a upstream.

Noticed the other day the trackpoint felt different on my P50, then
realized it was because rmi4 wasn't loading for this machine
automatically. Suspend/resume, hibernate, and everything else seem to
work perfectly fine on here.
