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] net: airoha: configure hw mac address according to the port
id
GDM1 port on EN7581 SoC is connected to the lan dsa switch.
GDM{2,3,4} can be used as wan port connected to an external
phy module. Configure hw mac address registers according to the port id.
