[POWERPC] add of_get_mac_address and update fsl_soc.c to use it
Add function of_get_mac_address(), which obtains the best MAC address to use from the device tree by checking various properties in order. The order is: 'mac-address', then 'local-mac-address', then 'address'. It skips properties that contain invalid MAC addresses, which were probably not initialized by U-Boot. Update gfar_of_init() and fs_enet_of_init() in fsl_soc.c to call of_get_mac_address(). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
