[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. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
