[igt-dev] [PATCH i-g-t] tests/kms_plane_lowres: Test only with one plane

[Mika Kahola]

The test is intended to test resolution changes from higher to
lower and back. We can test this with only one plane and we don't
need to run through all planes. This will save significant amount
of test execution time.
