[PATCH i-g-t v7 2/7] tests/kms_async_flips: limit #pipes tested during suspend

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

Test suspend on first and last pipe by default.

Alternatively test could be run on first and last CRTC; but due to pipe
reordering, this would result in using arbitrary pipes. Thus use first
and last hardware pipe when running suspend tests.

v6->v7
- use hardware pipe instead of CRTC (J-P, Jani)

v5->v6
- describe how pipe reordering affects the test (Jani)

v3->v4
- use crtc instead of display->crtcs (Thasleem)
- use proper logic operator (Thasleem)

v2->v3
- add missing S-O-B
