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.

Guest OS (e.g. Linux) may rely on a gap in E820 map in the 32-bit memory
space to determine the MMIO space for its PCI devices. Leave this gap
when building E820 map to keep the guest's PCI subsystem working.
After commit 7752d5cfe3d11ca0bb9c673ec38bd78ba6578f8e, Linux kernel no
longer requires the MMCONFIG region to be reserved in the E820 map.
Nonetheless, keep it in the reserved region to be on the safe side.

The ASL_COMPILER macro is hard coded as /usr/sbin/iasl, it is
complained by some developers. This patch changes it to a
flexible way, by which the following make command lines are
supported:
make
make devicemodel
make ASL_COMPILER=/path/to/iasl
make ASL_COMPILER=/path/to/iasl devicemodel

vHPET is used as a source of system timer by UEFI (e.g. OVMF).
This provides an alternative to using vPIT, which OVMF assumes is always
connected to vPIC.
This is ported from Bhyve, with a few changes:
- move to user space, using acrn_timer
- enable timers only when necessary
Origin: FreeBSD
License: BSD-3-Clause
URL: https://svnweb.freebsd.org/
commit: 326257
Purpose: Adding vHPET support.

NHLT table contains the settings some audio drivers need.
An ACPI method is used to get NHLT table address & length.
In current DM code, the NHLT talbe length in the ACPI method
is hardcoded, which will cause troubles when the length of the
table changed.
This patch replaces the hardcoded NHLT table length according to
the table length read from SOS.

When XSDT is created by DM, if audio passthru is enabled for
audio device (0:e:0), an entry is added in XSDT that references
the NHLT table. With this fix, NHLT appears in the kernel boot
log for ACPI and entry can be seen in /sys/firmware/acpi/tables/NHLT.

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.
