Currently cpufreq and xenpm are out of sync. Fix cpufreq reporting of if turbo mode is enabled or not. Fix xenpm to not decode for tristate, but a boolean.

Hi, This is the fifth version of this patch series. With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen relies on it to set the logical ID and the GIC, it won''t be possible to use Xen with this use case. This patch series is divided in 3 parts: - Patch 1: prepare Xen
