[PATCH i-g-t v2 0/4] Validate VF accesses to VRAM via BAR

[Lukasz Laguna]

Series includes a test to validate VF access to VRAM via BAR. The
following scenarios are covered:
- VF can access all provisioned memory via the VRAM BAR,
- VF cannot access memory beyond what's provisioned via the VRAM BAR,
- VF can access memory via the VRAM BAR after reprovisioning.

Additionally, it introduces a library for VRAM accesses and helper to
iterate over enabled VFs.

v2:
- apply changes in intel_vram lib based on Marcin's review,
- apply changes in xe_sriov_vram based on Piotr's and Marcin's review.

Detailed changelogs can be found in updated patches.
