Lukasz Maniak 44c2c09488 hw/nvme: Add support for SR-IOV 
This patch implements initial support for Single Root I/O Virtualization
on an NVMe device.

Essentially, it allows to define the maximum number of virtual functions
supported by the NVMe controller via sriov_max_vfs parameter.

Passing a non-zero value to sriov_max_vfs triggers reporting of SR-IOV
capability by a physical controller and ARI capability by both the
physical and virtual function devices.

NVMe controllers created via virtual functions mirror functionally
the physical controller, which may not entirely be the case, thus
consideration would be needed on the way to limit the capabilities of
the VF.

NVMe subsystem is required for the use of SR-IOV.
