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.

do you plan to add more chips to the mtk_is_hwlro_supporte() function ?
if not a simple

	eth->hwlro = (eth->chip_id == MT7623_ETH);

might be enough
