Subject: [PATCH v4 0/2] 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.

Changes since v3:
- rework architecture to allow future gdm{1,4} support
- read REG_INT_ENABLE() register in airoha_qdma_set_irqmask() to guarantee
  airoha_qdma_wr() complete in the spinlock critical section - thx Arnd for
  the clarification
- remove unnecessary wmb()
- remove debugfs
- move register definitions in .c and remove .h
- fix warnings
- enable NAPI thread by default
Changes since v2:
- rename airoha,en7581.yaml in airoha,en7581-eth.yaml
- remove reset dependency in airoha,en7581-eth.yaml
- remove airoha_dev_change_mtu() callback
Changes since v1:
- drop patch 2/3
- remove queue lock for rx queues
- add bql support
- add ethtool stats support
- fix possible infinite loop in airoha_qdma_rx_process routine
- always destroy page_pool in case of error during initialization
- cosmetics
