====================
net: ethernet: mediatek: check the hw lro capability by the chip id instead of the dtsi

The series modify to check if hw lro is supported by the chip id.

changes since v3:
- Refine mtk_is_hwlro_supported() function

changes since v2:
- Refine mtk_get_chip_id() function

changes since v1:
- Because hw lro started to be supported from MT7623, the proper way to check if the feature is capable is to judge by the chip id instead of by the dtsi.
