[RESEND v2 1/1] dt-bindings: soc: add vf610 reboot syscon controller

[RESEND v2 1/1] dt-bindings: soc: add vf610 reboot syscon controller

[Frank Li]

Add vf610 reboot controller, which used to reboot whole system. Fix below
CHECK_DTB warnings:

arch/arm/boot/dts/nxp/vf/vf610-bk4.dtb: /soc/bus@40000000/src@4006e000:
    failed to match any schema with compatible: ['fsl,vf610-src', 'syscon']

IC reference manual call it as system reset controller(SRC), but it is not
module as linux reset controller, which used to reset individual device.
SRC work as reboot controller, which reboot whole system. It provides a
syscon interface to syscon-reboot.

Change in v2
- change description to avoid confuse about reset controller.
- it is legacy device, more than 10 year. So try keep existed dts as it.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/soc/fsl/fsl,vf610-src.yaml: $id: 'http://devicetree.org/schemas//soc/fsl/fsl,vf610-src.yaml#' does not match 'http://devicetree.org/schemas(/[^/ ]+)+\\.yaml#'
	from schema $id: http://devicetree.org/meta-schemas/base.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250818183427.3601986-1-Frank.Li@nxp.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
