[PATCH] net: phy: phylink: fix SFP interface autodetection

[Baruch Siach]

When connecting a PHY to phylink use the detected interface. Otherwise,
the link fails to come up when the configured 'phy-mode' differs from
the SFP detected mode.

This fixes 1GB SFP module link up on eth3 of the Macchiatobin board that
is configured in the DT to "2500base-x" phy-mode.

Fixes: 9525ae83959b6 ("phylink: add phylink infrastructure")
