These should be singleton objects, otherwise things get problematic if
you have more than one switch device instantiated in the system.

Yes, I will update this.

Actually I think they need to be part of lan966x.
Because we want each lan966x instance to be independent of each other.
This is not seen in this version but is more clear in the next version
(v4).
