net: airoha: Fix IPv6 hw acceleration in bridge mode
ib2 and airoha_foe_mac_info_common have not the same offsets in
airoha_foe_bridge and airoha_foe_ipv6 structures. Current codebase does
not accelerate IPv6 traffic in bridge mode since ib2 and l2 info are not
set properly copying airoha_foe_bridge struct into airoha_foe_ipv6 one
in airoha_ppe_foe_commit_subflow_entry routine.
Fix IPv6 hw acceleration in bridge mode resolving ib2 and
airoha_foe_mac_info_common overwrite in
airoha_ppe_foe_commit_subflow_entry() and configuring them with proper
values.
