drm/i915/selftests: Exercise basic RPS interrupt generation

Since we depend upon RPS generating interrupts after evaluation
intervals to determine when to up/down clock the GPU, it is imperative
that we successfully enable interrupt generation! Verify that we do see
an interrupt if we keep the GPU busy for an entire EI.
