When the virtual PM port is written, we can infer that guest has just
initiated a poweroff action. So we send a poweroff event upon this port
write. The DM event handler will try to emit it (to Libvirt).
Developers can write app/script to decide what to do with this event.

Followed ACPI spec 4.8.2.5, if SCI_EN is set, the interrupt will be
routed to SCI interrupt logic. If SCI_EN is not set, the interrupt
will be routed to SMI interrupt logic.
ACRN does not support SMI for now, so check SCI_EN before trigger
SCI.

libevent have the exactly same issue. The issue is decripted here:
https://github.com/libevent/libevent/blob/master/whatsnew-2.1.txt
The fixing is:
We introduce a teardown callback to mevent and make sure there is
no race issue between callback and teardown call.
This patch updates the mevent API and the caller as well.

The current dm, all non-pci and non-acpi related files are put into
hw/platform directory. This is actually disturbed the meaning of
*platform*. The platform devices are mean of board and SoC specific
non-PCI devices, like usb devices, etc.
This patch refines the ACRN dm directory architecture.
For some common device logic files, likes block_if.c/uart_core.c or
usb_core.c. They will move to hw/ directly.
For platform architecture depended files, create arch/ under root dir.
And create sub-dir arch/x86 for x86 architecture, will create more
architectures in future. The pm.c will move to this new dir.
The hw/acpi will be moved to hw/platform/acpi due to acpi also be
considered as part of platform.
