[PATCH net-next v2 2/2] net: airoha: fix PSE memory configuration in airoha_fe_pse_ports_init()

[Lorenzo Bianconi <lorenzo@kernel.org>]

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")
