drm/i915: Make IS_GENx macros work on a mask
If instead of numerical comparison me make these test a bitmask, we enable the compiler to optimize all instances of IS_GENx || IS_GENy. v2: Make bit zero of gen mask mean gen 1. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
