Refactor Xen Support for Intel Turbo Boost
Refactor the existing code that supports the Intel Turbo feature to
move all the driver specific bits in the cpufreq driver. Create
a tri-state interface for the Turbo feature that can distinguish
amongst enabled Turbo, disabled Turbo, and processors that don't
support Turbo at all.
