[igt-dev] [PATCH i-g-t 09/11] tests/amdgpu/amd_plane: Add full screen scaling test case

[Stylon Wang <stylon.wang@amd.com>]

From: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com>

[Why]
Full screen scaling is a common usecase

[How]
Rework the scaling tests to add a 'fullscreen' test case. Change the
test_plane function to use "dst_w/h" instead of a scale multiplier. This
way we can easily add a full screen scale multiplier.
