sunxi: Add support for multiple ethadrr-esses
Currently we fill ethaddr with a fixed unique address based on the SoCs serial (from the sid) to make sure that boards which use the integrated emac / gmac get a fixed mac rather then a random one. On some boards the wifi does not come with a fixed mac either, so we need to also set eth1addr. This commit changes the ethaddr setting code to check for ethernet%d aliases (as fdt_fixup_ethernet does) and set an ethaddr variable for all present aliases.
