vpd: retrieve mac addresses and pass them to bootloader
Chrome OS devices firmware usually includes an area called VPD (Vital Product Data). VPD is a blob of a certain structure, in particular containing freely defined variable size fields. A field is a tuple of the field name and field contents. MAC addresses of the interfaces are stored in VPD as well. Field names are in the form of 'ethernet_macN', where N is the zero based interface number. This patch retrieves the MAC address(es) from the VPD and populates them in the coreboot table so that they become available to the bootloader. BUG=chrome-os-partner:32152, chromium:417117 TEST=with this and other patches in place the storm device tree shows up with MAC addresses properly initialized.
