Description
Description
The sequence has below scenario:
1). claim the mutex lock
2). write to transition registers and start lc transition.
But in automatic collected functional coverage group, the regwen = 1 is not collected.
I tagged it to V3 because clearly we have the sequence (otherwise we cannot create any lc transition). We just need to update csr mirrored value.

Research direction
Start with the sequence that claims the mutex lock, writes the transition registers, and starts the life-cycle transition, then trace the automatic functional coverage group and its CSR mirrored value. Done means coverage includes regwen = 1 and writes to locked registers for this existing scenario.
