[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.

Applies over previously sent acpi-cpufreq and software coordination
bug fix patch
