[PATCH i-g-t v1 0/2] Add platform-specific joiner exception mode handling

[Sowmiya S <sowmiya.s@intel.com>]

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.

  lib/igt_kms: Add platform-specific joiner exception mode handling
  lib/igt_kms: Skip joiner exception modes in boundary non-joiner search
