====================
dsa: Add support for the ethernet switch on the ESPRESSObin

This set of patches adds support for the Marvell Ethernet Topaz switch
family (88E6141/88E6341) which is found on the ESPRESSObin. With this
series the network is usable on this board.

As usual, I rebased the series on the very last net-next/master. In
this series there is no temperature support which need some patches
form Andrew Lunn.

As soon as Andrew Lunn will post the needed patch I will send a patch
to enable the temperature support.

Changelog:

v6 -> v7:
- rebased on net-next/master (5b8784aa)
- Fixed the wrong age time coeff from 15s to 3.75s.
- Remove support for temperature sensor

v5 -> v6:
- rebased on net-next/master (d140199a)
- Fix the redundant check on mv88e6xxx_6341_family (reported by Julia
  Lawall)
- Add support for the 88E6141
- Move support for temperature sensor in the phy part
