[PATCH net] net: ethernet: mtk_eth_soc: enable XDP support just for MT7986 SoC

[Lorenzo Bianconi]

Disable page_pool/XDP support for MT7621 SoC in order fix a regression
introduce adding XDP for MT7986 SoC. There is no a real use case for XDP
on MT7621 since it is a low-end cpu. Moreover this patch reduces the
memory footprint.
