net: ethernet: ti: ale: optimize ale entry mask bits configuartion
The ale->params.ale_ports parameter can be used to deriver values for all ale entry mask bits: port_mask_bits, port_mask_bits, port_num_bits. Hence, calculate above values and drop all hardcoded values. For port_num_bits calcualtion use order_base_2() API. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
