drm/xe: Add device flag to indicate SR-IOV support
The Single Root I/O Virtualization (SR-IOV) extension to
the PCI Express (PCIe) specification suite is supported
starting from 12th generation of Intel Graphics processors.
Add a device flag that we will use to enable SR-IOV specific
code paths and to indicate our readiness to support SR-IOV.
We will enable this flag for the specific platforms once all
required changes and additions will be ready and merged.
