[PATCH i-g-t v5 17/17] tests/kms_hdr: run on 3 outputs when testing suspend

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

Each suspend test is executed per output. Limit number of outputs tested
to 3 by default. Add command-line option enabling execution on every
output.

v3->v4
- declare `data' as static (Mohammed)
- add parenthesis around check (Mohammed)

v2->v3
- add patch
