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 2/2] net: airoha: fix PSE memory configuration in
airoha_fe_pse_ports_init()
Align PSE memory configuration to vendor SDK. In particular, increase
initial value of PSE reserved memory in airoha_fe_pse_ports_init()
routine by the value used for the second Packet Processor Engine (PPE2)
and do not overwrite the default value.
Introduced by commit 23020f049327 ("net: airoha: Introduce ethernet support
for EN7581 SoC")
