nic_uio: allow to bind any device

nic_uio: allow to bind any device

nic_uio requires the pci ids to be present in rte_pci_dev_ids.h in order to
bind the devices to nic_uio.  However, it's better to remove this whitelist
of pci ids, and instead rely on hw.nic_uio.bdfs kenv parameter to allow
binding any device to nic_uio.
