Support simple clock callouts

- Added new simple fault sensor to report clock faults
- Updated MRW parser to generate clock fault sensors
- Updated attribute definition to support clock fault sensors
- Initialize clock fault sensors when Hostboot starts
- Report clock fault to BMC when clock is called out
- Terminate system (config option) when clock is deconfigured
