Integrate this leaf with CPU policy handling, to leverage the host policy
when feature bits need evaluating.

1: cpu-policy: move invocation of recalculate_misc()
2: cpu-policy: define bits of leaf 6
3: include: de-assemblify cpuid.h
4: replace APERRMPERF synthetic feature bit
5: rename ARAT feature flag
6: Intel: use host CPU policy for ARAT checking
7: cpufreq: use host CPU policy for Turbo checking
8: cpufreq: use host CPU policy in HWP driver
