Now that vfio_pci has been split into two source modules, one focusing
on the "struct pci_driver" (vfio_pci.c) and a toolbox library of code
(vfio_pci_core.c), complete the split and move them into two different
kernel modules.
As before vfio_pci.ko continues to present the same interface under
sysfs and this change will have no functional impact.
Splitting into another module and adding exports allows creating new HW
specific VFIO PCI drivers that can implement device specific
functionality, such as VFIO migration interfaces or specialized device
requirements.

Please don't add driver versions to the upstream kernel, they useless.
Thanks
This just preserves the code for driver/module version that was in
vfio_pci.ko before the split.
However, this can be removed in V2 if we may need to have.
Right, we already agreed to preserve vfio_pci versioning scheme and
we'll not add it to new mlx5_vfio_pci or future drivers.
