Currently a VFIO driver's IOMMU capabilities are encoded as a series of
numerical defines. Replace this with an enum for future maintainability.

Allow to memory map the MMIO regions of the device so userspace can
directly access them. PIO regions are not being handled at this point.

The functions vfio_pci_virqfd_init and vfio_pci_virqfd_exit are not really
PCI specific, since we plan to reuse the virqfd code with more VFIO drivers
in addition to VFIO_PCI.

From: Antonios Motakis a.mota...@virtualopensystems.com
The Virqfd code needs to keep accesses to any struct *virqfd safe, but
this comes into play only when creating or destroying eventfds, so sharing
the same spinlock with the VFIO bus driver is not necessary.

The virqfd functionality that is used by VFIO_PCI to implement interrupt
masking and unmasking via an eventfd, is generic enough and can be reused
by another driver. Move it to a separate file in order to allow the code
to be shared.
