vfio/fsl-mc: Add VFIO framework skeleton for fsl-mc devices

This patch adds the infrastructure for VFIO support for fsl-mc
devices. Subsequent patches will add support for binding and secure
assigning these devices using VFIO.

FSL-MC is a new bus (driver/bus/fsl-mc/) which is different
from PCI and Platform bus.
