[PATCH i-g-t 0/6] Multi-tile support for xe_sriov_flr and related MMIO improvements

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

This series builds on Piotr Piórkowski’s v2 of the tile-aware VF FLR
test (see [1]) and reworks xe_sriov_flr test.

Main updates:
 - Move shared helper logic to lib/xe_query (tile helpers)
 - Refactor xe_sriov_flr test to use per-tile subchecks
 - Use proper MMIO initialization helpers (xe_mmio)
 - Keep verify_flr() template intact while isolating per-tile data
 - Simplify MMIO initialization/cleanup
 - Mark failed prerequisites to ensure CI detects them

Thanks to Piotr for the groundwork and earlier revisions.
