It certainly can be used, and it can be probed through a known PC-style
port number or through the DT binding.

However, we don't normally want it to try the PC style addresses, which
appear to be used in this case. This should only happen if
CONFIG_IPMI_SI_PROBE_DEFAULTS is set, as far as I can tell. Is that
set in your configuration?
