[Qemu-devel] [PATCH 5/5] target-i386: move cpu_reset and reset callback to cpu.c

[Igor Mammedov <imammedo@redhat.com>]

Moving reset callback into cpu object from board level and
resetting cpu at the end of x86_cpu_realize() will allow properly
create cpu object during run-time (hotplug) without calling reset exteraly.

When reset over QOM hierarchy is implemented, reset callback
should be removed.
