[PATCH v2] hwmon: (tmp401) Add of_match_table

[Camel Guo]

When tmp401 is built as kernel module, it won't be automatically loaded
even through there is a device node in the devicetree. e.g:
    i2c {
      #address-cells = <1>;
      #size-cells = <0>;

      sensor@4c {
        compatible = "ti,tmp401";
        reg = <0x4c>;
      };
    };
In order to make sure it is loaded automatically, this commit adds
of_match_table for tmp401.
