drivers/net/vsc9953: Add default configuration for VSC9953 L2 Switch

At startup, the default configuration should be:
 - enable HW learning on all ports (HW default);
 - all ports are VLAN aware;
 - all ports are members of VLAN 1;
 - all ports have Port-based VLAN 1;
 - on all ports, the switch is allowed to remove
   maximum one VLAN tag,
 - on egress, the switch should add a VLAN tag if the
   frame is classified to a different VLAN than the port's
   Port-based VLAN;
