Minor patch to the AR7 diag.sh to make the status LED a bit more useful. From the patch:

This setup gives us 3.5 distinguishable states:

- Solid OFF:  Bootloader running, or kernel hung (timer task stalled)
- Solid ON:   Kernel hung (timer task stalled)
- 5Hz blink:  preinit
- Heartbeat:  normal operation
