drm/amd/display: Test dm_helpers_is_dp_sink_present

Browse source

[WHAT]
Add a KUnit test for dm_helpers_is_dp_sink_present() that walks past the
early NULL checks and reaches the link service query.

A fake detect_dp_sink_present callback reports a sink, which covers the
DDC lookup and the return of the link service result.
