[igt-dev] [i-g-t v5 20/52] tests/kms_multipipe_modeset: Find the suitable mode instead of using default

[Bhanuprakash Modem]

As we are trying to run this subtest on all pipes + all outputs, It is not
possible to use 8K mode. To use 8K mode on a pipe then the consecutive pipe
must be free which is not true here.

Instead, reduce the resolution from 8K and run the test otherwise we'll endup
with the test failures.
