[U-Boot] sunxi: Add support for eth1addr

Currently we will already 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 (observed on 2 tablets using sdio rtl8703as wifi chips)
the wifi does not come with a fixed mac either, so also set eth1addr,
so that dts files can set an ethernet1 alias to get mac-address and
local-mac-address filled for dt nodes describing the wifi controller.

Oops, I forgot to update the commit msg and mark this as v2, I will
send a new version instead.

Regards,

Hans
