Subject: mvpp2: support fetching mac address from nvmem
The mvpp2 driver did not query nvmem for hardware mac addresses. This
patch adds querying of mac addresses stored in nvmem cells as a further
fallback option before assigning a random address.
Purposely added separately to fwnode_get_mac_address() above to maintain
existing behaviour with builtin adapter mac address still taking
precedence.
