Add a macro that specifies the format for printing CM_OBJECT_ID.
This allows to print the CM_OBJECT_ID is a consistent way in the
output logs.

In ACPI 6.4, s6.2.13, _PRT objects describing PCI legacy interrupts
can be defined following 2 models.
In the first model, _PRT entries reference link devices. Link devices
then describe interrupts. This allows to dynamically modify
interrupts through _SRS and _PRS objects and to choose exactly the
interrupt type (level/edge triggered, active high/low).
In the second model, interrupt numbers are described in the _PRT entry.
The interrupt type is then assumed by the OS.
AmlAddPrtEntry() currently only handles the first model. Make
changes to also handle the second model.

In ACPI 6.4, s6.2.13, _PRT objects describing PCI legacy interrupts

In the first model, _PRT entries reference link devices. Link devices
then describe interrupts. This allows to dynamically modify
interrupts through _SRS and _PRS objects and to choose exactly the
interrupt type (level/edge triggered, active high/low).
In the second model, interrupt numbder are described in the _PRT entry.
The interrupt type is then assumed by the OS.
The Arm BSA, sE.6 "Legacy interrupts" states that PCI legacy
interrupts must be converted to SPIs, and programmed level-sensitive,
active high. Thus any OS must configure interrupts as such and there
is no need to specify the interrupt type.
Plus it is not possible to dynamically configure PCI interrupts.
Thus remove the link device generation and use the second model
for _PRT.

Most ACPI tables for Kvmtool firmware are dynamically
generated. The AML code is also generated at runtime
for most components in appropriate SSDTs.
Although there may not be much to describe in the DSDT,
the DSDT table is mandatory.
Therefore, add an empty stub for DSDT.

From: Sami Mujawar <sami.mujawar@arm.com>
Add Configuration Manager to enable ACPI tables for Kvmtool
firmware. The Configuration Manager for Kvmtool uses the DT
Hardware Information Parser module (FdtHwInfoParser) to parse
the DT provided by Kvmtool. The FdtHwInfoParser parses the DT
and invokes the callback function HW_INFO_ADD_OBJECT to add
the Configuration Manager objects to the Platform Information
repository.
The information for some Configuration Manager objects may not
be available in the DT. Such objects are initialised locally
by the Configuration Manager.
Support for the following ACPI tables is provided:
- DBG2
- DSDT (Empty stub)
- FADT
- GTDT
- MADT
- SPCR
- SSDT (Cpu Hierarchy)
- SSDT (Pcie bus)

Notes:
v2:
- Only keep AARCH64 as a valid architecture. [Laszlo]
- Move modifications to ArmVirtKvmTool.dsc to the next
patch. [Laszlo]
- Various coding style/error handling/ASSERT corrections.
[Laszlo]
- Remove dependency to PcdForceNoAcpi and rely on DEPEX
to load the module. [Laszlo]
- Not possible to make 'struct PlatformRepositoryInfo'
an unamed struct since this is a redifinition.
[Laszlo/Pierre]
- Define 'FMT_CM_OBJECT_ID' print formatter in an earlier
patch and use it in this patch. [Laszlo/Pierre]
v3:
- Add address size limit for IORT PCI root complex. [Pierre]

From: Sami Mujawar <sami.mujawar@arm.com>
A Configuration Manager that uses the Dynamic Tables framework
to generate ACPI tables for Kvmtool Guests has been provided.
This Configuration Manager uses the FdtHwInfoParser module to
parse the Kvmtool Device Tree and generate the required
Configuration Manager objects for generating the ACPI tables.
Therefore, enable ACPI table generation for Kvmtool.

Notes:
v2:
- Remove Pcds that are redefined to their default value,
and modules already included in ArmVirtPkg/ArmVirt.dsc.inc
[Laszlo]
- Use guards as '!if $(ARCH) == AARCH64' to conditionnaly
generate ACPI tables. This allows to prevent the 32bits
ARM/ACPI combination without restricting the DynamicTablesPkg
to AARCH64. This means that KvmTool on ARM will use the DT.
Not adding Laszlo's Acked-by since this is not exactly what
was suggested. [Laszlo/Pierre]

Acpiview is a command line tool allowing to display, dump, or check
installed ACPI tables. Add a 'ACPIVIEW_ENABLE' switch to enable it
on an ArmVirt platform.
The switch is set for the ArmVirtKvmTool platform.

Notes:
v2:
- Only add AcpiView for ArmVirtKvmTool instead of all
ArmVirt platforms. This is done using a
'ACPIVIEW_ENABLE' switch. [Laszlo]
