introduce a new qom device to deal with panicked event
pvpanic device is used to send guest panic event from guest to qemu.
When guest panic happens, pvpanic device driver will write a event
number to IO port 0x505(which is the IO port occupied by pvpanic device,
by default). On receiving the event, pvpanic device will pause guest
cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.
