Subject: [PATCH net-next v2 2/2] net: airoha: npu: Add en7581-npu-7996
 compatible string

Introduce "airoha,en7581-npu-7996" compatible string in order to
specify different firmware binaries if the EN7581 SoC is running MT7996
(Eagle) chipset.
This is a preliminary patch to enable MT76 NPU offloading for MT7996
(Eagle) chipset since it requires different binaries with respect to
the ones used for MT7992 on the EN7581 SoC.
