mlxsw: Unified bridge conversion - part 3/6
This is the third part of the conversion of mlxsw to the unified bridge
model.
Like the second part, this patchset does not begin the conversion, but
instead prepares the FID code for it. The individual changes are
relatively small and self-contained with detailed description and
motivation in the commit message.

The function was designed to configure both VLAN and FID RIFs, but
currently the driver does not use VLAN RIFs. Instead, it emulates VLAN
RIFs using FID RIFs.
As part of the conversion to the unified bridge model, the driver will
need to use VLAN RIFs, but they will be configured differently from FID
RIFs.
As a preparation for this change, rename the function to reflect the
fact that it is specific to FID RIFs and do not pass the RIF type as an
argument.
This leaves mlxsw_reg_ritr_fid_set() unused, so remove it.

Currently, the driver emulates 802.1Q FIDs using 802.1D FIDs. As such,
the RIFs configured on top of these FIDs are FID RIFs and not VLAN RIFs.
As part of converting the driver to the unified bridge model, 802.1Q
FIDs and VLAN RIFs will be used.
As a preparation for this change, rename the emulated VLAN RIFs from
'MLXSW_SP_RIF_TYPE_VLAN' to 'MLXSW_SP_RIF_TYPE_VLAN_EMU'. After the
conversion the emulated VLAN RIFs will be removed.

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.

Currently, the only FID attributes that are edited after FID creation
are its VNI and NVE tunnel flood pointer. This is achieved by eventually
invoking mlxsw_sp_fid_vni_op() with an updated set of arguments.
In the future, more FID attributes will need to be edited, such as the
ingress RIF configured on top of the FID.
Therefore, it makes sense to encapsulate all the FID edit logic in one
function that will perform the edit based on an updated FID structure.
To that end, update the FID structure before invoking the various edit
operations that eventually call into mlxsw_sp_fid_vni_op(). Use the
updated structure as the sole argument of the edit operations.

In the unified bridge model, FID classification mappings (e.g., {Port,
VID}->FID) and layer 3 egress VID classification mappings (i.e., {eRIF,
ePort}->VID) will need to be updated when a RIF is configured on top of
a FID. This requires the driver to be aware of all the {Port, VID} pairs
mapped to a FID.
To that end, extend the FID structure with a linked list of {Port, VID}
pairs. Add an entry to the list when a {Port, VID} is mapped to a FID
and remove it upon unmap.
Keep the list sorted by local port as it will be useful for {eRIF,
ePort}->VID mappings via REIV register in the future.
