[igt-dev] [PATCH i-g-t v2 05/11] tests/amdgpu/amd_plane: Create mpo panning test

From: Bhawanpreet Lakha <Bhawanpreet.Lakha at amd.com>
[Why]
Moving the MPO window is a common usecase (video window being moved).
This test creates a MPO window and moves it horizontally, vertically and
diagonally
[How]
Create common video resolution windows and move them across the
displays. Test pass is determined by getting a crc of window location
using a single plane, then recreating this scenario using overlay.
Test panes from Start->End1, Start->End2 and Start->End3
CRTC#1

|Primary | --> |Primary | End1

|Primary | |Primary | End2
