[PATCH net-next v2] dt-bindings: net: Convert hisilicon,hns-mdio to DT schema

["Rob Herring (Arm)" <robh@kernel.org>]

Convert the hisilicon,hns-mdio binding to DT schema format. Add the
missing 'subctrl-vbase' property which is already in use.

Assisted-by: LLM
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
---
v2:
 - Make subctrl-vbase required and fix the register offset descriptions

-Hisilicon MDIO bus controller
-
-Properties:
-- compatible: can be one of:
-	"hisilicon,hns-mdio"
-	"hisilicon,mdio"
-  "hisilicon,hns-mdio" is recommended to be used for hip05 and later SOCs,
-  while "hisilicon,mdio" is optional for backwards compatibility only on
-  hip04 Soc.
-- reg: The base address of the MDIO bus controller register bank.
-- #address-cells: Must be <1>.
-- #size-cells: Must be <0>.  MDIO addresses have no size component.
-
-Typically an MDIO bus might have several children.
-
-Example:
-         mdio@803c0000 {
-                   #address-cells = <1>;
-                   #size-cells = <0>;
-                   compatible = "hisilicon,hns-mdio","hisilicon,mdio";
