After upgrading to guest kernel 6.1.80, it checks the CPPC V2 capability
in _OSC of DSDT. To support it for ACRN guest, add CPPC V2 capability in
_OSC of DSDT. Currently we only support CPPC V2 capability in _OSC of
DSDT.

For an elf-loaded or beImage-loaded User VM, acrn-dm is responsible for

After resume from S3, acrn-dm should read waking_vector and set related
registers to make guest to resume.

This patch does:
- define IASL_MIN_VER in the top-level Makefile and pass it Device Model
- verify the "iasl" version at run time
if "iasl" version is older than IASL_MIN_VER, refuse to launch the
post-launched VM and exit directly.

At run time (on the *target* machine), acrn-dm depends on "iasl" to build
the ACPI tables for post-launched VMs.
This patch does:
- remove the dependency on ASL_COMPILER, which would only be used at build time
- add a new acrn-dm parameter "--iasl <iasl_compiler_path>"
If "--iasl <iasl_compiler_path>" is specified as the acrn-dm parameter,
acrn-dm uses <iasl_compiler_path> as the path to the "iasl" compiler;
otherwise, "which iasl" is used to detect the "iasl" compiler.
If "iasl" is not found at run time, refuse to launch the post-launched VM
and exit directly.
v2 -> v3:
- use "strlen" rather than "strncmp" to check whether asl_compiler
has been set or not
v1 -> v2:
- remove "iasl_param" and "with_iasl_param" to simplify the logic

The GET_PLATFORM_INFO will be removed from hypervisor. The acrn-dm can
only refer to Service VM's resources from now, all the resources out of
Service VM are not awared by acrn-dm. The original info got from
GET_PLATFORM_INFO needs to changed to Service VM's perspective like lapic id.
The pcpu_id is the index of lapic instance in MADT table. This patch
parses the Service VM's MADT table to convert the pcpu_id to lapic_id instead
of GET_PLATFORM_INFO.

This patch enables TPM2 passthrough to post-launched VM with eventlog
support.
User starts by providing command line "--acpidev_pt <TPM2_HID>",
of which the <TPM2_HID> will be searched from /proc/iomem for TPM2 buffer
start address and size. Furthermore, If TPM2 eventlog is supported,
TPM2 eventlog information will be retrieved from sysfs TPM2 table and
passed-through as well.
v4 -> v5:
move tpm2 related logic from acpi.c to tpm.c

This patch prepares vRTCT for post-RTVM instead of
pass-thru native RTCT:
- Configurations are based on Service VM native RTCT.
- Remap vLAPIC IDs in vRTCT.
- Remap base address of SW SRAM memory regions
from HPA to GPA.
- HPA base of Software SRAM shall be parsed from PTCT
