Rafał Miłecki c60e9d1839 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.
