cr50_set_board_cfg() we definitely only want to do for Cr50, not Ti50 as it emits the longer interrupt pulses under all circumstances.

I think we do want to print the ti50 version in the log.  The existing cr50_ method can fulfill that purpose, though it does also try to parse a particular format.  Maybe I should create a separate ti50_get_firmware_version() ?
