airoha: Introduce EN7581 SoC support 
Introduce EN7581 SoC support with currently rfb board supported.

This is a new 64bit SoC from Airoha that is currently almost fully
supported upstream with only the DTS missing. Setting source-only
waiting for the full upstream support to be completed.

Subject: [PATCH 1/8] net: airoha: Introduce airoha_qdma struct
Introduce airoha_qdma struct and move qdma IO register mapping in
airoha_qdma. This is a preliminary patch to enable both QDMA controllers
available on EN7581 SoC.
