I believe better to keep "PMD" in config option for consistency:
CONFIG_RTE_LIBRTE_IFCVF_VDPA_PMD
And add this into PMD section of the doc.

Can be good to add comment that these can be same with virtio device id to
clarify this is known/expected.

No need to set name, already done by RTE_PMD_REGISTER_PCI

latest format is "pmd.net.ifcvf_vdpa"
