Chris Wilson 7ce5b6850b drm/i915/selftests: Use mul_u32_u32() for 32b x 32b -> 64b result
As realised by commit 9e3d6223d2 ("math64, timers: Fix 32bit
mul_u64_u32_shr() and friends"), GCC does not always generate ideal code
for performing a 32b x 32b multiply returning a 64b result (i.e. where
we idiomatically use u64 result = (u64)x * (u32)x).
