net: airoha: Add L2 hw acceleration support

Browse source

Similar to mtk driver, introduce the capability to offload L2 traffic
defining flower rules in the PSE/PPE engine available on EN7581 SoC.
Since the hw always reports L2/L3/L4 flower rules, link all L2 rules
sharing the same L2 info (with different L3/L4 info) in the L2 subflows
list of a given L2 PPE entry.
