Google tells me you have a
IEI Integration Corp DELL0817:00 044E:121F Touchpad 

and that this is a HID over I2C device, which requires the
following kernel modules:

intel-lpss-pci
i2c-hid
hid-multitouch

and then it will work.

My Stretch system has all three of those (4.9.0-8-amd64),
so try modprobing them all and see what results you get.
