[Qemu-devel] [PATCH 5/5] Cleanup unused global var qemu_system_powerdown

[Igor Mammedov <imammedo@redhat.com>]

All deps that used global qemu_system_powerdown var are now converted
to notifiers, so remove it.

Signed-off-by: Igor Mammedov <imammedo@redhat.com>

v2:
  - removed hunk with #include "hw/irq.h", for patch not to depend on
    cpu_as_device series.
  - reuse name of removed qemu_system_powerdown var as a function name
    for initiating system powerdown, by uninling monitor and notifiers
    call in it at the last commit to fix bisectability of series.
    Suggested-by: Paolo Bonzini <pbonzini@redhat.com>
