Display code uses IS_BATTLEMAGE macro but the platform support doesn't still exist in i915. So fake IS_BATTLEMAGE macro defined to enable building i915 code. We should make sure the macro parameter is used in the always-false expression so that we don't run into "unused variable" warnings from i915 builds if the IS_BATTLEMAGE() check is the only place the i915 pointer gets used in a function. While we're at it, also update the IS_LUNARLAKE macro to include the parameter in the false expression for consistency.
