Add documentation for the properties needed by the HiSilicon
6421v600 driver, and by the SPMI controller used to access
the chipset.

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

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/spmi/hisilicon,hisi-spmi-controller.example.dt.yaml: example-0: spmi@fff24000:reg:0: [0, 4294066176, 0, 4096] is too long

I was unable to find any way to solve this one. What's the proper
way to set the length of the root reg on some example?

The default is 1 address and size cell. Either adjust 'reg' for that
or you can define a bus node:

bus {
  #address-cells = <2>;
  #size-cells = <2>;

  spmi@123 {
    ...
  };
};

My preference is doing the former.
