P-state software coordination for ACPI core

Many non-ACPI systems are filling this field by mistake, which makes its usage
confusing. Lets clean it.

I haven't looked at the cpufreq code recently but remember
that it was needed to ensure that all the CPU which
share clock/voltage gets updated (affected cpus) on
freq change. The CPUs which needs SW co-ordination, should
have this flag enabled and OMAP was falling in that category.
May be I miss-understood its use, but can you confirm that
SW co-ordination logic continues to work without this flag ?
