bcm53xx: set WAN MAC address to don't share one with LAN interface
After analyzing numerous NVRAMs and vendor firmwares it seems the base MAC address is used for LAN interface. WAN interface has different one which sometimes is set directly in NVRAM and sometines needs to be calculated. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
