From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Some time ago we stopped letting the compiler merge code like IS_SKYLAKE ||
IS_KABYLAKE || IS_... into a single conditional in all cases. This series
quickly restores that for a nice overall saving and hopefully with a bearable
impact on the code base.

Tvrtko Ursulin (3):
drm/i915: Add IS_PLATFORM macro
drm/i915: Compact device info access by a small re-ordering
drm/i915: Allow optimized platform checks
