Daniel Golle 8730f9e536 generic: move accepted patches for mtk_eth_soc to backport-6.6
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.
