drm/i915: Add missing include file <linux/math64.h> 

Fix build error:
./drivers/gpu/drm/i915/selftests/i915_random.h: In function i915_prandom_u32_max_state:
./drivers/gpu/drm/i915/selftests/i915_random.h:48:23: error:
 implicit declaration of function mul_u32_u32; did you mean mul_u64_u32_div? [-Werror=implicit-function-declaration]
  return upper_32_bits(mul_u32_u32(prandom_u32_state(state), ep_ro));
