[PATCH i-g-t 2/3] kms_plane: Update for universal plane changes

[Matt Roper <matthew.d.roper@intel.com>]

Recent changes in igt_kms to support universal planes have removed the
plane list order guarantees that kms_plane depended upon.  Ensure that
we loop over the entire plane list properly and then selectively skip
non-overlay planes.

While we're at it, update a couple igt_output_get_plane() calls to use
plane enums rather than integer values to make it clear what we're
actually doing.
