PGT, a port-group table is an in-HW block of specialized memory that holds
sets of ports. Allocated within the PGT are series of flood tables that
describe to which ports traffic of various types (unknown UC, BC, MC)
should be flooded from which FID. The hitherto-used layout of these flood
tables is being replaced with a more flexible scheme, called compressed FID
flooding (CFF). CFF can be configured through CONFIG_PROFILE.flood_mode.

In this patch, add MLXSW_CMD_MBOX_CONFIG_PROFILE_FLOOD_MODE_CFF, the value
to use to enable the CFF mode.
