net: mtk_eth_soc: move and correct link timer programming
Program the link timer appropriately for the interface mode being used, using the newly introduced phylink helper that provides the nanosecond link timer interval. The intervals are 1.6ms for SGMII based protocols and 10ms for 802.3z based protocols.
