Enable the intel_pstate driver for Haswell CPUs and one Ivy Bridge model not already included (0x3E). I've been testing this change on the Core i5-4200u (model 0x45) and I referenced the list of models in tools/power/x86/turbostat/turbostat.c:has_nehalem_turbo_ratio_limit to determine the others.

Nak for now.
We have not completed our testing on these CPUs. I would like to
get my testing done before I start seeing issues from the field come
in.
If this patch were to hangout in testing for a while it would not
hurt my feelings there it could only hurt those that knew what
they were getting into :-)
