net: sun8i_emac: Fix PHY initialization

The previous code tried to update the PHY parameters without waiting for
autonegotiation to complete. This caused wrong values to be written to
the EMAC in sun8i_adjust_link(). As a result, any commands that called
eth_start() before autonegotiation completed would find the network
nonfunctional. Fix this by using the correct function to start up the
PHY.
