CHASSIS2 architecture never fix clock groups for Cluster and hardware
accelerator like PME, FMA. These are SoC defined. SoC defines :-
- NUM of PLLs present in the system
- Clusters and their Clock group
- hardware accelerator and their clock group
if no clock group, then platform clock divider for FMAN, PME
