Since these pins should not have changed from one kernel version to another, it
doesn't explain how my device "jumped" from I2C2 to I2C1.  I'm debugging this now.

I believe this is wrong.  The chip documentation says that the pin controlled by
I2CSPAN selects which of the two inputs to use.  It does not bridge.
