mlxsw: reg: Add 'flood_rsp' field to SFMR register
SFMR register creates and configures FIDs. As preparation for unified
bridge model, add a field for future use.
In the new model, RITR no longer configures the rFID used for sub-port RIFs
and it has to be created by software via SFMR. Such FIDs need to be created
with special flood indication using 'flood_rsp' field. When set, this bit
instructs the device to manage the flooding entries for this FID in a
reserved part of the port group table (PGT).
