generic: move accepted patches for mtk_eth_soc to backport-6.6

Browse Source 
In preparation to update to upcoming Linux 6.6.33 move accepted patches
from mediatek target to backport folder, so moving to newer Linux 6.6
releases becomes easier and also other patches on top can be applied
more easily.

Subject: [PATCH net-next 1/2] net: ethernet: mediatek: split tx and rx fields
in mtk_soc_data struct
Date: Wed, 8 May 2024 11:43:34 +0100
Subject: [PATCH] net: ethernet: mediatek: split tx and rx fields in
mtk_soc_data struct
Split tx and rx fields in mtk_soc_data struct. This is a preliminary
patch to roll back to QDMA for MT7986 SoC in order to fix a hw hang
if the device receives a corrupted packet.
patch to roll back to ADMAv1 for MT7986 and MT7981 SoC in order to fix a
hw hang if the device receives a corrupted packet when using ADMAv2.0.

Subject: [PATCH net-next 2/2] net: ethernet: mediatek: use QDMA instead of
ADMAv2 on MT7981 and MT7986

Subject: [PATCH] net: ethernet: mediatek: use ADMAv1 instead of ADMAv2.0 on
MT7981 and MT7986
ADMA is plagued by RX hangs which can't easily detected and happen upon
receival of a corrupted package.
Use QDMA just like on netsys v1 which is also still present and usable, and
doesn't suffer from that problem.
ADMAv2.0 is plagued by RX hangs which can't easily detected and happen upon
receival of a corrupted Ethernet frame.
Use ADMAv1 instead which is also still present and usable, and doesn't
suffer from that problem.
