mlxsw: reg: Add ingress RIF related fields to SVFA register
SVFA register controls the VID to FID mapping and {Port, VID} to FID
mapping for virtualized ports. As preparation for unified bridge model,
add some required fields for future use.
On ingress, after ingress ACL, a packet needs to be classified to a FID.
The key for this lookup can be one of:
1. VID. When port is not in virtual mode.
2. {RQ, VID}. When port is in virtual mode.
3. FID. When FID was set by ingress ACL.
Since RITR no longer performs ingress configuration, the ingress RIF for
the first two entry types needs to be set via new fields in SVFA -
'irif_v' and 'irif'.
Add the two mentioned fields for future use and increase the length of
the register accordingly.
