dt-bindings: marvell: Add Marvell MV88E6060 DSA schema 



The Marvell MV88E6060 is one of the oldest DSA switches from
Marvell, and it has DT bindings used in the wild. Let's define
them properly.

It is different enough from the rest of the MV88E6xxx switches
that it deserves its own binding.

description:

  The Marvell MV88E6060 switch has been produced and sold by Marvell

  since at least 2008. The switch has one pin ADDR4 that controls the

  MDIO address of the switch to be 0x10 or 0x00, and on the MDIO bus

  connected to the switch, the PHYs inside the switch appear as

  independent devices on address 0x00-0x04 or 0x10-0x14, so in difference

  from many other DSA switches this switch does not have an internal

  MDIO bus for the PHY devices.

    description:

      The MV88E6060 is the oldest Marvell DSA switch product, and

      as such a bit limited in features compared to later hardware.
