as it can help CI to track track troubles.

Add support for it.

v4:
- patch 1 broke on two patches, to reduce git diff, making
  easier to review;
- addressed some nitpicks on patch 4.

v3:
- no changes. Just rebased due to a merge conflict.

v2:

- added a patch (already submitted) to shut-up i915 trybot to
  try to run those tests when i915 driver is loaded;
- removed duplication of the unwanted drivers array and declare
  it as const with const strings;
- reordered includes and removed a duplication;
- did some cosmetic changes.

Mauro Carvalho Chehab (4):
  intel-ci: update blacklists to work with the Xe driver
  intel-ci: create a symlink for i915-blacklist.txt
  lib/igt_kmod: add support for Xe driver
  xe/xe_module_load: add a test to load/unload Xe driver
