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.
