[igt-dev] [PATCH i-g-t v2 2/2] tests/kms_flip: Change 2x tests execution order

[Mika Kahola]

In order to optimize execution of kms_flip binary mode tests, let's change
the execution order so that 2x tests will be executed after basic tests.

On GLK platform with 1 display, the patch reduced the execution time by
2 seconds on average (2X tests were skipped). As these 2X tests are meant
to run with 2 display configuration the expected reduction in time on test
execution will be higher.
