drivers: net: fsl-mc: Include MAC addr fixup to DPL
Previous to MC v10.x, port mac address was specified via DPL. Since newer MC versions are compatible with old style DPLs, make the u-boot env mac addresses visible there. This applies only to DPLs that have an older version. DPLs use 32 bit values for specifying MAC addresses. U-boot environment variables take precedence over the MAC addresses already visible in the DPL/DPC.
