Yu Wang b838e9b720 dm: pm: mask the higher bits of parameter of smi_cmd handler
Windows will set 0x262a0 for smi cmd pio, need to mask the higher bits
due to smi command is 8 bits register. Otherwise, it cause the
ACPI_ENABLE case can't be matched, and windows expecting the SCI_EN of
PM1_CONTROL be set after switch to ACPI mode. Finally, cause windows
trigger panic.

Kaige Fu c4ec7ac358 DM: Keep consistency between HV and DM about PM1A_CNT_ADDR
To keep consistency between HV and DM about PM1A_CNT_ADDR,
it is better to replace the PM1A_CNT related MACROs used in DM
with VIRTUAL_PM1A_CNT related MACROs in acrn_common.h.

Yuan Liu 35dfadc98e dm: check SCI_EN bit of pm1_control before trigger SCI
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.

Yuan Liu 566e8824da dm: power button emulation by acrnctl command.
when UOS is running, "acrnctl suspend vm" and "acrnctl stop vm" commands are
able to trigger a SCI interrupt, then UOS enters sleep or shutdown according
to the default behavior of the power button. The default behavior is based on
UOS power button setting.

Yuan Liu 8e8ed07dd7 dm: implement power button for power managerment
Listen to power button state via /dev/input/event0. When the power
button is pressed, then set PWRBTN_STS bit. If PWRBTN_EN is set, the
sci interrupt is triggered.

For suspend or shutdown of UOS by power button, needs UOS to configure
the default behavior of the power button.

Yin Fengwei 64d9c59aa1 dm: enhence the mevent API
There is one race issue between mevent callback (which is called
in mevent_dispatch thread) and mevent_delete (which could be called
in dev thread). And the callback is called after mevent_delete.

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.

after UOS enter S3.

Also add general pm.c and move pm related function to this file.

Yu Wang 8c06b69622 dm: Reorganize ACRN DM directory.
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.
