[igt-dev] [PATCH v2 4/4] tests/amdgpu/amd_psr: add PSR-SU scaling test cases

[why]
We need test cases to validate PSR-SU disabled when a specific
plane scaling occurs by visual confirm. From driver's perspective,
any plane's height/width change detected, it would cause PSR-SU
be disabled.

[how]
- based on the existed MPO test case, we'd add two more input
  arguments to the test function, i.e. one as flag indicating if
  to test scaling, another as scaling ratio for the primary plane
- start from 1/3 iteration in test run, scaling the primary plane
  w/ the given ratio and update the overlay as well, and observe
  if PSR-SU is disabled as expected by allowing some delay to
  check
- add two sub-test cases, one w/ scaling ratio 1.5, another 0.75
