    xen/cpufreq: move "init" flag into common structure
    
    AMD cpufreq cores will be intialized in two modes, legacy P-state mode,
    and CPPC mode. So "init" flag shall be extracted from px-specific
    "struct xen_processor_perf", and placed in the common
    "struct processor_pminfo". Otherwise, later when introducing a new
    sub-hypercall to propagate CPPC data, we need to pass irrelevant px-specific
    "struct xen_processor_perf" to just set init flag.
