[PATCH] intel_pstate: Add Haswell CPU models

[Nell Hardcastle <nell@spicious.com>]

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.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=60211
