[U-Boot] [PATCH] net: mvpp2: support setting hardware addresses from ethernet core

[Matt Pelland <mpelland@starry.com>]

mvpp2 already has support for setting MAC addresses but this
functionality was not exposed to the ethernet core. This commit exposes
this functionality so that MAC address assignments stored in U-Boot's
environment are correctly applied before Linux boots.
