Introduce Airoha NPU support to MT7996 driver. NPU is used to enable
traffic forward offloading between the MT76 NIC and the Airoha ethernet one
available on the Airoha EN7581 SoC using Netfilter Flowtable APIs.

Changes in v2:
- Rebase on top of wireless-next main branch
- This patch is based on the following commit avaiable in net-next main
branch but not in wireless-next one:
commit 105ce7ad57e492b75ab40f2dc591db645fadbaa2
