Like for Ethernet ports, the OcteonTx crypto engines must first be unbound
from their kernel module, then rebound to vfio-pci, before being usable
in DPDK.

As this capability is detected at runtime by dpdk-pmdinfo, add the info
in the PMD registering directives.

Then an external script can be used for bind and unbind.

[Anoob] The subject has to start with "crypto/octeontx: ...". Please correct this.

Also, please use OCTEON TX instead of OcteonTx here and in the description below.

[Anoob] Only the following change is required. Can you send a revised patch with this change?

RTE_PMD_REGISTER_PCI_TABLE(CRYPTODEV_NAME_OCTEONTX_PMD, pci_id_cpt_table);
+RTE_PMD_REGISTER_KMOD_DEP(CRYPTODEV_NAME_OCTEONTX_PMD, "vfio-pci");
