drm/amd/display: Add KUnit tests for amdgpu_dm_quirks

Browse source

Add KUnit test file amdgpu_dm_quirks_test.c covering retrieve_dmi_info().

Three test cases are provided:
- Verify aux_hpd_discon_quirk is reset to false even when previously true
- Verify edp0_on_dp1_quirk is reset to false even when previously true
- Verify both quirks remain false on a zero-initialised dm when no
  DMI match is found (expected in UML/KUnit environment)

Register the new test object in the tests/Makefile under
CONFIG_DRM_AMD_DC_KUNIT_TEST.
