Merge branch 'introduce-en7581-ethernet-support' 

Lorenzo Bianconi says:

====================
Introduce EN7581 ethernet support

Add airoha_eth driver in order to introduce ethernet support for
Airoha EN7581 SoC available on EN7581 development board.
EN7581 mac controller is mainly composed by Frame Engine (FE) and
QoS-DMA (QDMA) modules. FE is used for traffic offloading (just basic
functionalities are supported now) while QDMA is used for DMA operation
and QOS functionalities between mac layer and the dsa switch (hw QoS is
not available yet and it will be added in the future).
Currently only hw lan features are available, hw wan will be added with
subsequent patches.
