I do not expect this path to be taken for a guest device. IDE is not
relevant for TDIs in the guest and function0 is not a requirement guest
BDFs. I still need to add this to samples/devsec/, but the expectation
is that in "TVM mode" the presence of PCI_EXP_DEVCAP_TEE is sufficient
to route any PCI function to tsm_ops->probe().
