523dfa96ad drm/tests: reduce drm_mm_test stack usage 
The check_reserve_boundaries function uses a lot of kernel stack,
and it gets inlined by clang, which makes __drm_test_mm_reserve
use even more of it, to the point of hitting the warning limit:

drivers/gpu/drm/tests/drm_mm_test.c:344:12: error: stack frame size (1048) exceeds limit (1024) in '__drm_test_mm_reserve' [-Werror,-Wframe-larger-than]

When building with gcc, this does not happen, but the structleak
plugin can similarly increase the stack usage and needs to be
disabled, as we do for all other kunit users.

44a3928324 drm/tests: Add Kunit Helpers 
As the number of kunit tests in KMS grows further, we start to have
multiple test suites that, for example, need to register a mock DRM
driver to interact with the KMS function they are supposed to test.

Let's add a file meant to provide those kind of helpers to avoid
duplication.

542bbaa736 drm/tests: Order Kunit tests in Makefile 
Since we've recently added a ton of tests, the list starts to be a bit
of a mess and creates unneeded conflicts.

Let's order it alphabetically.

8f45610491 drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_rgb332() 
Test the conversion from XRGB8888 to RGB332.

What is tested?

 - Different values for the X in XRGB8888 to make sure it is ignored
 - Different clip values: Single pixel and full and partial buffer
 - Well known colors: White, black, red, green, blue, magenta, yellow
   and cyan
 - Other colors: Randomly picked
 - Destination pitch

How to run the tests?

 $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/tests \
         --kconfig_add CONFIG_VIRTIO_UML=y \
         --kconfig_add CONFIG_UML_PCI_OVER_VIRTIO=y
