[igt-dev] [PATCH] tests/intel/i915_pipe_stress: Use only first pipe if Bigjoiner is used

[Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>]

We currently are having test failures for Bigjoiner, because that
test tries to use all pipes simultaneously, not realizing that
if we use a Bigjoiner mode on pipe A, the adjacent pipe won't be
available.
For now just fix it by using only one pipe, if resolution > 3840
is detected.
