[CPUFREQ] Workaround for BIOS bug in software coordination of frequency
Some buggy BIOSes do a "software any" kind of coordination without telling about it to OS. So, when OS sets frequency on one CPU on these platforms, it will also impact all the other logical CPUs that are in the same power domain. Attached patch is a workaround for those buggy BIOSes. Patch should be a noop on the normal non-buggy platforms.
