[igt-dev] [PATCH v4 4/7] tests/kms_plane_alpha_blend: Limit the execution to single pipe & two planes

[Nidhi Gupta <nidhi1.gupta@intel.com>]

From: Bhanuprakash Modem <bhanuprakash.modem@intel.com>

As the execution is taking more time, limit the execution to single pipe
and two (first & last) planes.
