- add atom to p4-clockmod for thermal mgmt benefits for the atom
  procs that don't do freq scaling (lookin' at you, atom 330)

cpufreq: add atom family to p4-clockmod

Some atom procs don't do freq scaling (such as the atom 330 on my own
littlefalls2 board). By adding the atom family here, we at least get
the benefit of passive cooling in a thermal emergency. Not sure how
to see that its actually helping any, but the driver does bind and
claim its functioning on my atom 330.
