vfio/pci: Cleanup Kconfig
It should be possible to select vfio-pci variant drivers without building vfio-pci itself, which implies each variant driver should select vfio-pci-core. Fix the top level vfio Makefile to traverse pci based on vfio-pci-core rather than vfio-pci. Mark MMAP and INTX options depending on vfio-pci-core to cleanup resulting config if core is not enabled. Push all PCI related vfio options to a sub-menu and make descriptions consistent.
