rockchip: tinker: set ethaddr in late init
Set ethernet mac address in late init for Tinker Board, prevents getting a random mac address each boot. Read mac address from eeprom, first 6 bytes from m24c08@50. Same as /etc/init.d/rockchip.sh on Tinker OS. Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Simon Glass <sjg@chromium.org>
