drivers/hwmon/coretemp.c: enable the Intel Atom

Enable the coretemp driver on an Intel Atom.

I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load).  Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.
