This series enables support for PCI SR-IOV capabilty for PVH domains.
It allows Dom0 to enable and use SR-IOV virtual functions and for this
functions to be passed to guests.

To achieve this, handlers for SRIOV_CONTROL register and simplified handlers
for VFs header were implemented.

Core functionality is based on previous works [1] and [2].

Xen relies on dom0 to enable SR-IOV and call PHYSDEVOP_pci_device_* to inform
about addition/removal of VFs.

Tested on R-Car Spider board with Samsung NVMe SSD Controller 980 and Intel
X550T ethernet card.
