igd is related to the vfio_pci pci_driver implementation, move it out of
vfio_pci_core.c.
This is preparation for splitting vfio_pci.ko into 2 drivers.

Split the vfio_pci driver into two logical parts, the 'struct
pci_driver' (vfio_pci.c) which implements "Generic VFIO support for any
PCI device" and a library of code (vfio_pci_core.c) that helps
implementing a struct vfio_device on top of a PCI device.
vfio_pci.ko continues to present the same interface under sysfs and this
change should have no functional impact.
Following patches will turn vfio_pci and vfio_pci_core into a separate
module.
This is a preparation for allowing another module to provide the
pci_driver and allow that module to customize how VFIO is setup, inject
its own operations, and easily extend vendor specific functionality.
At this point the vfio_pci_core still contains a lot of vfio_pci
functionality mixed into it. Following patches will move more of the
large scale items out, but another cleanup series will be needed to get
everything.

The vfio_device structure is embedded into the vfio_pci_core_device
structure, so there is no reason for not including the header file in
the vfio_pci_core header as well.

This is another preparation patch for separating the vfio_pci driver to
a subsystem driver and a generic pci driver. This patch doesn't change
any logic.

This is a preparation patch for separating the vfio_pci driver to a
subsystem driver and a generic pci driver. This patch doesn't change any
logic.
The new vfio_pci_core_device structure will be the main structure of the
core driver and later on vfio_pci_device structure will be the main
structure of the generic vfio_pci driver.
