dt-bindings: arm: mediatek: topckgen: Convert to DT schema

Browse Source 
Convert topckgen bindings to DT schema format. MT2701, MT7623 and
MT7629 device trees currently have the syscon compatible without
it being mentioned in the old DT bindings file which introduces
dtbs_check errors when converting to DT schema as-is, so
mediatek,mt2701-topckgen and mediatek,mt7629-topckgen are placed
in the last items list with the syscon compatible, and syscon is
added to the mediatek,mt7623-topckgen list.

Mediatek topckgen controller
============================
The Mediatek topckgen controller provides various clocks to the system.
Required Properties:
- compatible: Should be one of:
- "mediatek,mt2701-topckgen"
- "mediatek,mt2712-topckgen", "syscon"
- "mediatek,mt6765-topckgen", "syscon"
- "mediatek,mt6779-topckgen", "syscon"
- "mediatek,mt6797-topckgen"
- "mediatek,mt7622-topckgen"
- "mediatek,mt7623-topckgen", "mediatek,mt2701-topckgen"
- "mediatek,mt7629-topckgen"
- "mediatek,mt7986-topckgen", "syscon"
- "mediatek,mt8135-topckgen"
- "mediatek,mt8167-topckgen", "syscon"
- "mediatek,mt8173-topckgen"
- "mediatek,mt8183-topckgen", "syscon"
- "mediatek,mt8516-topckgen"
- #clock-cells: Must be 1
The topckgen controller uses the common clk binding from
Documentation/devicetree/bindings/clock/clock-bindings.txt
The available clocks are defined in dt-bindings/clock/mt*-clk.h.
Example:
topckgen: power-controller@10000000 {
compatible = "mediatek,mt8173-topckgen";
reg = <0 0x10000000 0 0x1000>;
#clock-cells = <1>;
};
