ath79: use "fixed-layout" for Embedded Wireless devices
Those devices have Ethernet interfaces using base MAC address increased by 0x40 in the 3rd indexed byte (00:00:00:FF:00:00). To describe that we were using a custom (downstream) "mac-address-increment-byte" property. The same result can be achieved by using "mac-base" with a properly adjusted offset value (0x40 << 16). It may be not pretty but it should work without custom property or downstream kernel patch to support it.
