dt-bindings: phy: Convert Calxeda ComboPHY binding to json-schema

Calxeda Highbank Combination Phys for SATA

Properties:

- compatible : Should be "calxeda,hb-combophy"

- #phy-cells: Should be 1.

- reg : Address and size for Combination Phy registers.

- phydev: device ID for programming the combophy.

Example:

	combophy5: combo-phy@fff5d000 {

		compatible = "calxeda,hb-combophy";

		#phy-cells = <1>;

		reg = <0xfff5d000 0x1000>;

		phydev = <31>;

	};

title: Calxeda Highbank Combination PHYs binding for SATA

description: |

  The Calxeda Combination PHYs connect the SoC to the internal fabric

  and to SATA connectors. The PHYs support multiple protocols (SATA,

  SGMII, PCIe) and can be assigned to different devices (SATA or XGMAC

  controller).

  Programming the PHYs is typically handled by those device drivers,

  not by a dedicated PHY driver.
