    xen/cpufreq: normalize hwp driver check with hwp_active()
    
    Instead of using hypercall passing parameter to identify hwp driver,
    we shall use hwp_active(). Also, we've already used hwp_active() in
    do_get_pm_info() in the same file to do hwp driver check, it's
    better syncing with same way.
