[igt-dev] [PATCH i-g-t] tests/kms_atomic_transition:reduce execution time

[Nidhi Gupta]

kms_atomic_transition test is taking minimum of
69.5s time to execute on CI. To reduce the execution
time this patch will add the change which will run
the test on 1 HDR plane, 1 SDR UV plane, 1 SDR Y plane
and skip the rest of the planes.
