[PATCH 3/3] dt-bingings: pinctrl: Convert UniPhier pin controller to json-schema

[Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>]

Convert the UniPhier pin controller binding to DT schema format.

Signed-off-by: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>

In the original .txt file, there is a description:
The UniPhier pinctrl should be a subnode of a "syscon" compatible node

I did not figure out how to represent (or check) it in dt-schema.
I just moved it to a comment line in 'examples'.
If there is a better way, please let me know.

-Required properties:
-- compatible: should be one of the following:
-    "socionext,uniphier-ld4-pinctrl"  - for LD4 SoC
-    "socionext,uniphier-pro4-pinctrl" - for Pro4 SoC
-    "socionext,uniphier-sld8-pinctrl" - for sLD8 SoC
-    "socionext,uniphier-pro5-pinctrl" - for Pro5 SoC
-    "socionext,uniphier-pxs2-pinctrl" - for PXs2 SoC
-    "socionext,uniphier-ld6b-pinctrl" - for LD6b SoC
-    "socionext,uniphier-ld11-pinctrl" - for LD11 SoC
-    "socionext,uniphier-ld20-pinctrl" - for LD20 SoC
-    "socionext,uniphier-pxs3-pinctrl" - for PXs3 SoC

-Note:
-The UniPhier pinctrl should be a subnode of a "syscon" compatible node.
