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

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

this interface to display the GUI of installer when setup a refresh

a) If the MMIO device only has MMIO regions and no ACPI Table touched, using

b) If the MMIO device touches ACPI Table, using "--acpidev_pt HID"
Now only support TPM2 MSFT0101 MMIO device pass through through launch script
using "--acpidev_pt MSFT0101". When we want to pass through the TPM2 deivce,
we would not allow to emulate the vTPM2 at the same time. This is becuase
the ACRN-DM emulate the TPM2 as MSFT0101 too. Otherwise, the VM can't boot.
Besides, we could only support one TPM2 device PT and one MMIO device PT.
For TPM2 device PT, the MMIO resources are hard-coded. For the MMIO device PT,
we could pass through the MMIO resources on the cmdline.
ToDo:
1. We may use HID to discover the MMIO regions and ACPI Table instaed of
hard-coded.
2. To identify a MMIO device only by MMIO regions.
3. To allocate virtual MMIO regions in a reserved guest MMIO regions.
