The initial plane vblank wait operates on display registers, so it really belongs in the display code proper. Move it there. We can use intel_parent_irq_enabled() to determine if we can rely on interrupts or not. On average we should end up waiting half a frame here, so the polling interval can be fairly long. 1 ms (which actually makes poll_timeout_us() use ~250-1000 usec) seems good enough to me.
