[PATCH] drm/amd/display: Drop KUnit tests for removed parse_hdmi_amd_vsdb()

parse_hdmi_amd_vsdb() was removed when HDMI FreeSync detection moved to
the common EDID parser, but its declaration and KUnit tests remained,
breaking modpost:

  ERROR: modpost: "parse_hdmi_amd_vsdb" [...connector_test.ko] undefined!

Remove the stale declaration and the three dead test cases.

Fixes: f65198b3d073 ("drm/amd/display: Use HDMI FreeSync range from common EDID parser")
