    powerd: Wait hw.acpi.cpu.px_dom* sysctl to be created by kernel
    
    Since hw.acpi.cpu.px_dom* creation is queued into ACPI taskqueue
    and ACPI taskqueue is shared across various ACPI modules, any delay
    in other modules may cause hw.acpi.cpu.px_dom* to be created at
    quite a later time (e.g. cmbat module's task could take quite a lot
    of time).
