The OpenCompute timecard driver has additional functionality besides
a clock.  Make the following resources available:

 - The external timestamp channels (ts0/ts1)
 - devlink support for flashing and health reporting
 - GPS and MAC serial ports
 - board serial number (obtained from i2c device)

Also add watchdog functionality for when GNSS goes into holdover.
