[igt-dev] [PATCH i-g-t 2/4] tests/kms_psr2_su: Set the damaged clip in page flips

[José Roberto de Souza]

Without this i915 will not know what was updated in the screen and
update the whole plane causing mismatch between the read SU blocks and
the expected value when PSR2 selective fetch is enabled.
