sb/intel/ibexpeak: Update debug code to match other chips

Other chips dump tco_status here if it wasn't handled, which makes
    sense.

tco_sts can't be zero here, because the call would have already returned
    if it were.  Also, dump_tco_status wouldn't print anything if tco_sts
    were zero.

This will still only print the debug information if DEBUG_SMI is
    enabled in Kconfig, so in general, this change won't have much of an
    effect on anything.
