drm/amd/display: add KUnit tests for freesync config

Browse source

[WHAT]
Add KUnit tests for get_freesync_config_for_crtc and
reset_freesync_config_for_crtc using a shared connector/crtc/stream
fixture. Cover the writeback early return, the not-capable and
out-of-range unsupported paths, the active-variable, inactive and
active-fixed states, and the config reset.
