[PATCH i-g-t v2 00/10] Xe SR-IOV admin scheduling helpers and test updates

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

This v2 series introduces a generic helper for sysfs "choice" attributes
and wires Xe SR-IOV scheduling helpers and tests to the SR-IOV admin
sysfs interface.

Patches 1–2 add igt_sysfs_choice and unit tests for parsing and
formatting enumerated sysfs values such as sched_priority.
Patches 3–4 convert the existing sched_priority helpers in
xe_sriov_provisioning into thin wrappers around igt_sysfs_choice.
Patch 5 adds a small PF/VF sysfs path helper used by the SR-IOV code.
Patch 6 exposes SR-IOV admin sysfs accessors for execution quantum,
preemption timeout, scheduling priority, VF stop and restoring defaults,
following recent kernel changes:

Patches 7–10 update the xe_sriov_scheduling and xe_pmu tests to prefer
the admin interface, improve cleanup, and add coverage for SR-IOV
admin sysfs scheduling attributes in xe_sriov_admin_profile.

v2:
- Added generic igt_sysfs_choice helper and unit tests.
- Reworked sched_priority helpers to use igt_sysfs_choice wrappers.
- Introduced igt_sriov_func_str() PF/VF sysfs path helper.
- Extended SR-IOV admin helpers with scheduling accessors.
- Updated xe_sriov_scheduling and xe_pmu to prefer SR-IOV admin sysfs.
- Added xe_sriov_admin_profile tests for admin sysfs scheduling
  attributes (defaults, write->readback, bulk updates).
