[POWERPC] 4xx: Enable EMAC for PPC405 Walnut board
This patch enables the ibm_newemac driver for the Walnut board. It fixes the
device tree for the walnut board to order the MAL interrupts correctly and
adds the local-mac-address property to the EMAC node. The bootwrapper is also
updated to extract the MAC address from the OpenBIOS offset where it is stored.
