[Intel-gfx] [PATCH 12/42] drm/i915/lnl: Add display definitions

[Lucas De Marchi]

From: Balasubramani Vivekanandan <balasubramani.vivekanandan at intel.com>

Add Lunar Lake platform definitions for i915 display. The support for
LNL will be added to the xe driver, with i915 only driving the display
side. Therefore define IS_LUNARLAKE to 0 to disable it when building the
i915 module.
