[PATCH v2 i-g-t 0/5] Add debugfs SR-IOV helpers; Improve clear-lmem check

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

This patch series introduces SR-IOV debugfs and provisioning helpers
to allow enhance test coverage.

The following changes are included:

1. Add helper for opening SR-IOV debugfs attributes:
   Helper allows to open SR-IOV debugfs attributes corresponding to
   specified PF device, VF number, and GT number.

2. Define shared resource types and provisioned range structure:
   Add shared resource enumeration, provisioned range structure definition,
   and provide a function to convert shared resource enums to their string
   representation.

3. Add function to read provisioned ranges from debugfs:
   Implement xe_sriov_pf_debugfs_read_provisioned_ranges() to read and
   parse VFs provisioned shared resource ranges from the debug filesystem.
   Introduce xe_sriov_debugfs_provisioned_attr_name() to get the debugfs
   attribute name for a given shared resource type.

4. Improved clear-lmem subcheck in xe_sriov_flr test:
   Read and verify full LMEM ranges using the lmem_provisioned debugfs
   attribute in the clear-lmem subcheck.

5. Extract the function to search for GGTT provisioned PTE ranges for each
   VF from test/xe_sriov_flr to a library file lib/xe/xe_sriov_provisioning.
   This refactoring improves code reusability and will allow to prepare a
   test comparing debugfs exposed ggtt_provisioned attribute.
