drm/i915: drop unused non-i915 IS_<PLATFORM> macros

The IS_LUNARLAKE(), IS_BATTLEMAGE(), and IS_PANTHERLAKE() macros were
added for compatibility with the xe driver, for display needs, even
though i915 does not support the platforms in question. Display has
since moved away from the macros, and they are no longer needed. Remove.
