[PATCH v2 i-g-t 0/4] tests/intel/xe_sriov_vfio: Add basic VFIO coverage

[Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com>]

Add xe_sriov_vfio test covering basic xe-vfio-pci module handling
and VFIO smoke-test paths for SR-IOV VFs.

The first patch adds standalone module load/unload subtest. The second
adds a dynamic bind-unbind-vfs subtest that enables VFs and binds each
of them to xe-vfio-pci through driver_override. The remaining patches
add basic VFIO coverage by opening the VFIO group and querying VFIO
region information for a VF bound to xe-vfio-pci.

v2:
- Keep as a single load/unload subtest skipping
  when module already loaded (Lukasz)
- Split bound-driver assertion helper and remove
  redundant pre-bind unbind (Lukasz)
- Simplify restore_xe_vfio_module() logic (Lukasz)
