[igt-dev] [PATCH 2/2][V4] tests/kms_universal_plane: Skip offscreen test for universal API

[Alex Hung <alex.hung@amd.com>]

amdgpu driver intentionally rejects plane outside of the screen and thus
this test is skipped on AMD HW. See more details in kernel commits
40d916a2602c and 4abdb72bd8576 which are summarized as below:

"Reject this condition (too small viewport size) at validation time.
This gives the calling level a chance to handle this gracefully and
avoid inconsistent behaviors."
