[igt-dev] [PATCH i-g-t v5 0/3] xe/xe_module_load: add a test to load/unload Xe driver

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

It is interesting to let IGT to unload/reload the Xe driver,
as it can help CI to track track troubles.

Add support for it.

v5:
- minimized the first patch and dropped the symlink one.

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.
