SVC watchdog should be disabled when device is entering suspend mode.
Testing done:
- Sanity tested on EVT1.5
- Check no SVC ping during the suspend process
- Check SVC watchdog is back on pinging once device is resumed

Sometimes you want to disable the SVC watchdog without having to patch
your kernel, so provide a sysfs file to do this. This can let us do
power measurements, and let the firmware developers not go crazy
worrying that the kernel is going to reset their chips with no notice.

Now that we have a svc ping command, let's add a watchdog to call it
every so often (1 second at the moment.) If it finds something went
wrong, post a stern message to the kernel log and call:
start unipro_reset
to reset the whole greybus hardware subsystem.
