[PATCH i-g-t v6 2/7] tests/kms_async_flips: limit #crtcs tested during suspend

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

Increase tests' performance by testing only 2 CRTCs by default.

Currently first and last CRTC coincide with first and last pipe. In
future this is likely to change due to pipe reordering. It should not
affect the test overall since the aim is to pick two arbitrary CRTCs.

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

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

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