Non builtin constant passed as timeout parameter to _wait_for_atomic() macro
causes build break under GCC 4.4.7 due to BUILD_BUG_ON that checks upper bound.
Switch into MAYBE_BUILD_BUG_ON as it can correctly determine parameter class.
Fixes: 1d1a9774 ("drm/i915: Extend intel_wait_for_register_fw() with fast timeout")
