[PATCH i-g-t v1 04/16] tests/kms_async_flips: limit #outputs tested during suspend

["Michał Grzelak" <michal.grzelak@intel.com>]

We are iterating through each output while testing suspend. This results
in extended execution time. In turn this leads to hitting CI enforced
timeout.

By default limit number of tested outputs to 2. Test each connected
output when passing command-line parameter.
