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 1/2] net: airoha: read default PSE reserved pages value before
updating
Store the default value for the number of PSE reserved pages in orig_val
at the beginning of airoha_fe_set_pse_oq_rsv routine, before updating it
with airoha_fe_set_pse_queue_rsv_pages().
Introduce airoha_fe_get_pse_all_rsv utility routine.
Introduced by commit 23020f049327 ("net: airoha: Introduce ethernet support
for EN7581 SoC")
