Check the BC0 lock status in the configuration sequence
Description
During the TCDS LPM reload tests, it was noticed that the TTC stream from the AMC13 to the CTP7 can be corrupted. It is however not warned until starting (and blocking) a run. We should check the TTC stream validity status during the configuration, once the clock and TTC streams are declared stable. In particular, the BC0 lock is a good indicator.
Possible fixes
Check the BC0 lock after the clocks reset and TTC configuration. Would the BC0 be unlocked or unstable, the FSM must go to the Error state.
