dt-bindings: phy: Convert Northstar 2 PCIe PHY to YAML

Convert the Broadcom Northstar 2 PCIe PHY Device Tree binding to YAML
and rename it accordingly in the process since it had nothing to do with
a MDIO mux on the PCI(e) bus. This is a pre-requisite to updating
another binding file to YAML.

-Required bus properties:
-- reg: MDIO Bus number for the MDIO interface
-- #address-cells: must be 1
-- #size-cells: must be 0
-
-Required PHY properties:
-- compatible: should be "brcm,ns2-pcie-phy"
-- reg: MDIO Phy ID for the MDIO interface
-- #phy-cells: must be 0

-This is a child bus node of "brcm,mdio-mux-iproc" node.

-Example:
-
-mdio@0 {
-       reg = <0x0>;
-       #address-cells = <1>;
-       #size-cells = <0>;
