eth: mtk-eth: fix incorrect read of phy-handle
In mt7629-rfb.dts, the phy-handle is a reference to the node phy0, not the node itself: phy-handle = <&phy0>; phy0: ethernet-phy@0 { reg = <0>; } However the driver used ofnode_find_subnode("phy-handle") to read the node. It will always fail. This patch replaces ofnode_find_subnode with dev_read_phandle_with_args to make sure the node can be read correctly.
