[Qemu-devel] [PATCH qom-next 12/12] target-i386: move reset callback to cpu.c and call cpu_reset() in x86_cpu_realize()

[Igor Mammedov]

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).

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

Additionally, there is only call to cpu_x86_init() left in pc_new_cpu(),
move it into pc_cpus_init() and delete empty pc_new_cpu().
