mvebu: Turris Omnia: use SFP module, if present
Follow the recommendations stated in the Turris Omnia DTS for eth2:
"In case SFP module is present, U-Boot has to enable the sfp node above,
remove phy-handle property, and add managed = "in-band-status" property."
The boot script is written in a way, that it works for all U-Boot
versions deployed by the vendor so far (2015.10-rc2, 2019.07).
