mlxsw: spectrum_fid: Split a helper out of mlxsw_sp_fid_flood_table_mid()

Browse Source 
In future patches, for CFF flood mode support, we will need a way to
determine a PGT base dynamically, as an op. Therefore, for symmetry,
split out a helper, mlxsw_sp_fid_pgt_base_ctl(), that determines a PGT base
in the controlled mode as well.

Now that the helper is available, use it in mlxsw_sp_fid_flood_table_init()
which currently invokes the FID->MID helper to that end.
