In commit 53cb55b20208 ("drm/lima: handle spurious timeouts due to high irq latency") a check was added to detect an unexpectedly high interrupt latency timeout. With further investigation it was noted that on Mali-450 the pp bcast irq may also be a trigger of race conditions against the timeout handler, so add it to this check too.
