mlxsw: spectrum: Use different arrays of FID families per-ASIC type
Egress VID for layer 2 multicast is determined from two tables, the MPE
and PGT tables. The MPE table is a two dimensional table indexed by local
port and SMPE index, which should be thought of as a FID index.
In Spectrum-1 the SMPE index is derived from the PGT entry, whereas in
Spectrum-2 and newer ASICs the SMPE index is a FID attribute configured
via the SFMR register.
The validity of the SMPE index in SFMR is influenced from two factors:
1. FID family. SMPE index is reserved for rFIDs, as their flooding is
handled by firmware.
2. ASIC generation. SMPE index is always reserved for Spectrum-1.
As such, the validity of the SMPE index should be an attribute of the FID
family and have different arrays of FID families per-ASIC type.
As a preparation for SMPE index configuration, create separate arrays of
FID families for different ASICs.
