I don't know if there is a solid reason that we can not expose the
hwmon interface. But just like the comment says, "/* No hwmon because
there might be hwmon drivers registering */", given that of_thermal
just parses THERMAL data of device tree, it is reasonable to me for
exposing thermal interfaces only.
