vfio/pci: Split the pci_driver code out of vfio_pci_core.c
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.
