On NVL (display_ver=35), a higher max_dotclock causes modes like
6144x3456@60 to pass the standard igt_bigjoiner_possible() checks,
yet the kernel still enables joiner for them. Introduce per-platform
exception mode lists (e.g. nvl_joiner_exception_modes[]) dispatched
via novalake check in a new mode_needs_joiner_exception() helper, and
wire it into igt_bigjoiner_possible().
Fix intel_boundary_non_joiner_mode_found() to skip exception modes,
preventing test_basic_max_non_joiner from incorrectly selecting a
joiner-required mode as a non-joiner boundary mode.
