hwdb: Lenovo T490 Synaptics Touchpad hwdb entry

Browse Source 
The Synaptics Touchpad that comes with the T490 doesn't explicitly set
its resolution, so these lines are needed to provide that, in order to
help the libinput code detect overly large jumps.  Since this device
contains buttons under the lower section of the touchpad, large jumps
are common, so having the resolution helps libinput greatly reduce
the number of occurances of pointer jump.

This comes from
https://gitlab.freedesktop.org/libinput/libinput/issues/402.
