drm/amd/display: share common DM KUnit helpers

Browse source

Move fixture setup that was duplicated across several amdgpu_dm
KUnit tests into amdgpu_dm_kunit_helpers.c:

- dm_kunit_alloc_dc_with_ctx() allocates a dc and its dc_context.
- dm_kunit_alloc_drm_with_connector_list() allocates a drm_device
  with an initialized connector list.

Update the irq, psr, crtc and backlight tests to use these helpers.
