[U-Boot] [PATCH v2 32/45] net: mvpp2: Handle eth device naming in multi-CP case correctly

[Stefan Roese]

Currently, the naming of the ethernet ports is not handled correctly in
the multi-CP (Communication Processor) case. On Armada 8k, the slave-CP
also instantiates an ethernet controller with the same device ID's.
This patch now takes this into account and adds the required base-id
so that the slave-CP ethernet devices will be named "mvpp2-3 ...".

This patch also updates my Copyright notice to include 2017 as well.
