Add functions for managing the lan9303 ALR (Address Logic
Resolution).
Implement DSA methods: port_fdb_add, port_fdb_del, port_mdb_prepare,
port_mdb_add and port_mdb_del.
Since the lan9303 do not offer reading specific ALR entry, the driver
caches all static entries - in a flat table.

When both user ports are joined to the same bridge, the normal
HW MAC learning is enabled. This means that unicast traffic is forwarded
in HW.
If one of the user ports leave the bridge,
the ports goes back to the initial separated operation.
Port separation relies on disabled HW MAC learning. Hence the condition
that both ports must join same bridge.
Add brigde methods port_bridge_join, port_bridge_leave and
port_stp_state_set.

Indirect access (PMI) to phy register only work in I2C mode. In
MDIO mode phy registers must be accessed directly. Introduced
struct lan9303_phy_ops to handle the two modes.

The SMSC/Microchip LAN9303 is an ethernet switch device with one CPU port
and two external ethernet ports with built-in phys.
This driver uses the DSA framework, but is currently only capable of
separating the two external ports. There is no offload support yet.
