[igt-dev] [PATCH i-g-t] tests/kms_plane_multiple.c: Enhance the IGT test to enable multiple planes and multiple pipe.

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

In Existing kms_plane_multiple we are testing Multiple plane position on
one pipe at a time, we do not have a testcase where all the pipes are
enabled at the same time and checking for the plane positions.

Adding a subtest with all the pipes enabled and performing a test to
check the multiple plane positions with all the pipes at the same time. Clearing
of the resources are done after performing plane position test on all pipes.
