PS5: 
There is one thing I'm not 100% sure about for this commit.
Some SNB/IVB chips have more than 4 cores, namely 8. Some (Xeon series) even have more, but I'm not sure if coreboot supports those.
From reading Intel's public manual "Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 4: Model-Specific Registers", MSR_TURBO_RATIO_LIMIT comes in two "flavors", one for 4 core chips and one for 8.
The only difference is that the latter uses the 32 high bits while the former has them reserved.
As it is, this commit makes no distinction between the two and only writes to the lower 32 bits.
Thus, users of chips with 8 or more cores would be unable to configure the multipliers for more than 4 cores.
