Like for Ethernet ports, the OCTEON TX 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.

Fixes: bfe2ae495ee268 ('crypto/octeontx: add PMD skeleton')

V2: only "vfio-pci" is needed by this PMD
