[PATCH net-next v2 06/10] dt-bindings: net: define phylink bindings

["Arınç ÜNAL" <arinc.unal@arinc9.com>]

Define the phylink bindings on ethernet-controller.yaml and replace the
bindings on the dsa-port.yaml schema with them. The shared ports of DSA
requires phy-mode so keep that.

Important remarks about the phylink bindings:
- fsl,fman-dtsec uses tbi-handle instead of pcs-handle, therefore
  tbi-handle is included.
- For sfp, only managed with the in-band-status value must be required, but
  phy-handle is required as another option because of a special case on the
  eth2 node on arch/arm/boot/dts/marvell/armada-385-turris-omnia.dts.
