Before converting to the phylink interface, the init function would have
set a non-reserved I/F mode in the maccfg2 register. After converting to
phylink, 0 is written as mode, which is a reserved value (although it's
the hardware default). Without a valid mode, a SGMII link is never
established between the MAC and the PHY and thus .link_up() is never
called which could set the correct mode according to the actual speed.
Fix it by setting the maximum speed of the phy_interface_t in use in
.mac_config() - just like the driver did before the phylink conversion.
