drm/i915: Allow optimized platform checks
If we store the platform as a bitmask, and convert the
IS_PLATFORM macro to use it, we allow the compiler to
merge the IS_PLATFORM(a) || IS_PLATFORM(b) || ... checks
into a single conditional.
As a secondary benefit this saves almost 1k of text:

+1459260 60026 3656 1522942 173cfe drivers/gpu/drm/i915/i915.ko
v2: Removed the infamous -1.
