While this makes things better, it's not correct. The i2c2 bus does not use the
trackpad pin. I would believe a better way is to have a node that holds both
trackpads and claims the pin for both at once. And that node not being the i2c bus
as there could be more devices on the bus and the pin would be taken regardless of
any trackpad probing , which is not right.
Another option is to disable parallel probing for the trackpads, such that when one
fails to probe, the pin is released and can be taken by the other one.
