    acpi/cstate: Match C-states of the hyperthreads on the same core
    
    Some stupid BIOSes set different C-states for hyperthreads on the same
    core, which prevents the core from entering deep C-states, since not
    all hyperthreads of the core are in the deep C-states.
    
    We fix this by using same number of C-states for hyperthreads on the
    same core; the hyperthread w/ more C-states is taken as master.
