net: mtk_eth_soc: add out of band forcing of speed and duplex in pcs_link_up

Browse Source 
Add support for forcing the link speed and duplex setting in the
pcs_link_up() method for out of band modes, which will be useful when
we finish converting the pcs_config() method. Until then, we still have
to force duplex for 802.3z modes to work correctly.
