Why? tpm-chip is for chip functions and tpm-interface is for command
issuing functions, the startup command sequencors seem appropriately
placed...
These are still module private functions.

We already have two drivers that auto probe, you don't think there
will be more? The idea is to try and remove these low level entry
points so drivers are simpler.
TIS doesn't use it because it needs to get things setup in advance for
interrupt auto-probing, which is a very TIS unique thing.
Alternatively we can drop the auto-probe from nuvoton and force it to
rely on compatible string matching to enter TPM2 mode.
