<7>[   91.805388] [drm:intel_psr_compute_config [i915]] PSR2 not
enabled, resolution 3840x2160 > max supported 3640x2304

It failed because the GEN9 PSR2 HW only supports resolutions up to
3640x2304, so it switched back go PSR1 and the test failed because it
was expecting a PSR2 state not a PSR1.

I talked with DK, he thinks that the panel should be replaced in that
machine so we can have some PSR2 test coverage in GEN9.

If not possible we should add more code in igt_fixture() to check if
PSR2 is supported but that could potentially hide PSR2 issues behind
tests skipped or whitelist PSR2 tests in fi-whl-u.
