hwmon: (coretemp) Add support for Atom CE4110/4150/4170

Browse source 
commit 1102dcab84 upstream.

TjMax for the CE4100 series of Atom CPUs was previously reported to be
110 degrees C.

cpuinfo logs on the web show existing CPU types CE4110, CE4150, and CE4170,
reported as "model name : Intel(R) Atom(TM) CPU CE41{1|5|7}0 @ 1.{2|6}0GHz"
with model 28 (0x1c) and stepping 10 (0x0a). Add the three known variants
to the tjmax table.
