mlxsw: Remove multicast ID configuration

With respect to a firmware change, the Switch Multicast ID (SMID)
register is no longer needed, so the related configuration code can be
removed.

* --------------------------
* In multi-chip configuration, each device should maintain mapping between
* Multicast ID (MID) into a list of local ports. This mapping is used in all
* the devices other than the ingress device, and is implemented as part of the
* FDB. The MID record maps from a MID, which is a unique identi- fier of the
* multicast group within the stacking domain, into a list of local ports into
* which the packet is replicated.
