Different Spherion variants use different trackpads on the same I2C2 bus. Instead of enabling all of them by default, mark them as "fail-needs-probe" and let the implementation determine which one is actually present. Additionally, move the trackpad pinctrl entry back to the individual trackpad nodes.
