[PATCH v2] hwmon: (tmp401) Add of_match_table

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.
