This should be copied from Linux kernel UAPI includes.
The version used here is Linux 5.1.0
We define a new device region in vfio.h to be able to
get the ZPCI CLP information by reading this region from
userland.
We create a new file, vfio_zdev.h to define the structure
of the new region we defined in vfio.h
