[igt-dev] [RFC, i-g-t] Added Dynamic Subtest

[nidhi1.gupta at intel.com]

From: Nidhi Gupta <nidhi1.gupta at intel.com>

In kms_plane_scaling have a subtest with 2 pipe it
will execute it weather 2 pipes are available or not.
Later it has to be analysed and discard it as valid skip.
To save this time updated in test to first check the available
outputs and then execute the test
