PEL: Add FanControllerOffline message reg entry

This error is posted when the fan monitor application cannot find any
fan sensors on D-Bus, so it doesn't know the fan states when a power on
is attempted.  It will shut down the system.

The P0-T12 and P0-T17 callouts are connectors for the fan signal cable.
These callouts follow the rules of using a symbolic FRU to identify the
cable for the first endpoint and a 'CBLCONT' symbolic FRU for the other
one.
