We need to register and trigger CPU reset manually for hotplugged
CPU. Besides, we gather CPU reset handlers of all CPUs because CPU
reset should happen before GIC reset.

(cherry picked from commit e38ab50a87d6f581d282e606ac12db5e8238c1e1)
This series is an attempt to provide CPU hotplug support on ARM
virt platform. This is based on ACPI GED device.
We should enable ACPI support, and use vGICv3 and 64bit CPU to
support CPU hotplug.
Under KVM accel, the KVM vCPUs is pre-created. Besides, vGIC IRIs
is pre-created too. However, QEMU vCPU objects are defer-created.
