Mac ID is to be filled by U-Boot and this kind of approach is already
rejected in linux-omap list.

If proper ethaddr/eth*addr is populated in U-boot environment variable
then mac-address dt property in ethernet* device nodes will be populated
before boot kernel in U-boot. So I don't think this patch series is
required.
