touchpad: add a special quirk for the Lenovo x220 with updated firmware
If an x220 is updated to the touchpad firmware version 8.1, the touchpad
suffers from the same issues as the x230 and needs custom acceleration code.
Unfortunately we cannot detect this otherwise, so it is left to the user as a
custom hwdb setting.
