ohci: fix resource cleanup leak
When hot-unplugging the usb controllers (ehci/uhci),
we have to clean all resouce of these devices,
involved registered reset handler. Otherwise, it
may cause NULL pointer access and/or segmentation fault
if we reboot the guest os after hot-unplugging.
Let's hook up reset via DeviceClass->reset() and drop
the qemu_register_reset() call. Then Qemu will register
and unregister the reset handler automatically.
Ohci does't support hotplugging/hotunplugging yet, but
existing resource cleanup leak logic likes ehci/uhci.
