Subject: vc/amd/opensil/genoa_poc/mpio: add debug output for unused chip

Print that the MPIO chip of one of the MPIO-related PCI device functions
is unused and is skipped, if the type is IFTYPE_UNUSED and the
corresponding PCI device function isn't enabled. This allows to
differentiate between this case and the case where the type isn't
IFTYPE_UNUSED.
