[igt-dev] [PATCH i-g-t 1/3] tests/kms_busy: Limit the execution to two pipes

To save the CI time, we can restrict the execution to two pipes
i.e first and last active pipes.
If we want to execute on all pipes, we need to pass an extra
argument "-e" indicates extended.
Example: ./build/tests/kms_busy -e --r basic
V2, V3:
* Fix the typo in args handler (Petri)
V4:
* Handle clampling cleanly (Petri)
* Restore lost test coverage in the previous version (Petri/Bhanu)
V5:
* Fix two subtest with the name "basic" (Petri)
V6:
* Refactor to run on first & last pipes.
