Like for OCTEON TX, the OCTEON TX2 crypto engines must
first be unbound from their kernel module, then rebound to
vfio-pci, before being used 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: 2f8a1b963eb77 ("crypto/octeontx2: add PMD skeleton")
