Subject: [PATCH net-next 1/4] net: dsa: ocelot: populate supported_interfaces

Populate the supported interfaces bitmap for the Ocelot DSA switches.

Since all sub-drivers only support a single interface mode, defined by
ocelot_port->phy_mode, we can handle this in the main driver code
without reference to the sub-driver.
