net: dsa: microchip: ksz8795: use port_cnt instead of TOTOAL_PORT_NUM

To get the driver working with other chips using different port counts the dyn_mac_table should be flushed depending on the amount of available ports. This patch remove the extra define TOTOAL_PORT_NUM and is making use of the dynamic port_cnt variable instead.
