ARM: dts: stm32: Add nvmem-cells to ethernet nodes for constant mac-addresses

The efuse device tree description already has the two labels pointing to
the efuse nodes that specify the mac-addresses to be used. Wire them up
to the ethernet nodes. This is enough to make barebox pick the right
mac-addresses and pass them to Linux.
