[igt-dev] [PATCH] tests/kms_setmode: Add comment for valid scenario

[Jeevan B <jeevan.b@intel.com>]

Describe the valid scenario for 'basic-clone-single-crtc' and
'basic-clone-single-crtc' tests, as these tests are skipped if
a valid scenario is not found, which can cause confusion during
bug analysis.
