Subject: [PATCH net-next 12/14] mlxsw: spectrum_fid: Extract SFMR packing into a helper

Both mlxsw_sp_fid_op() and mlxsw_sp_fid_edit_op() pack the core of SFMR the
same way. Extract the common code into a helper and call that. Extract out
of that a wrapper that just calls mlxsw_reg_sfmr_pack(), because it will
be useful for the dummy family later on.
