kirkwood: remove upstreamed patch

Upstream solution came with 6.4. Seems quilt refreshed it to the extent
that it basically gets applied twice.

-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.
