[PATCH v4 01/15] xen/cpufreq: move "init" flag into common structure

[Penny Zheng]

AMD cpufreq cores will be intialized in two modes, legacy P-state mode,
and CPPC mode. So "init" flag shall be extracted from specific
"struct xen_processor_perf", and placed in the common
"struct processor_pminfo".
