[TG3]: Improve ASF heartbeat.
Change to a different ASF heartbeat message code to improve reliability. There were some reports of unintended resets on real time kernels where the timer may be slow and cause the heartbeat to be late. Netpoll will also have the same problem because the timer irq will be unavailable. Using the new heartbeat code, the ASF firmware will also check the ring condition before resetting the chip when the heartbeat is expiring.
