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 IS_NOVALAKE() in a new mode_needs_joiner_exception() helper, and wire it into igt_bigjoiner_possible(). Also add IS_NOVALAKE() to intel_chipset.h as a combined IS_NOVALAKE_S() || IS_NOVALAKE_P() macro. 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.
