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 patch is to eliminate kernel error msgs:
'ACPI Error: AE_NOT_FOUND, Evaluating _PSS'
This is caused by missing of _PSS table in guest ACPI. It would
happen when pstate is not injected to the guest.
Kernel ACPI pstate driver first probes
_PPC(performance capabilites) and _PCT(performance control)
in ACPI. If they exist, then it loads the _PSS(performance state).
If _PPC/_PCT are presented while _PSS is missing, it prints
the error msg.
In acrn-dm, _PPC/_PCT are hard-coded to all vCPUs, while _PSS
are constructed with the pCPUs' pstate data. This is base on
assumption that all VMs can have pstate.
Now the pstate is given to VM only when the VM is not sharing
any CPU(and no RTVM is setup in the scenario).
When the VM doesn't have pstate, the hypercall will return px_cnt=0,
and the _PSS is not constructed. In this case, _PPC/PCT should not
be injected, too.

pass-through the whole pSRAM to one RTVM, so we will also pass-
through the PTCT to the very same RTVM. This function will
read the native PTCT from SOS and inject it into post-

We could add MMIO device pass through by two ways:
a) If the MMIO device only has MMIO regions and no ACPI Table touched, using
"--mmiodev_pt MMIO_regions",
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.

Some OSes assume the platform must have the IOAPIC. For example:
Linux Kernel allocates IRQ force from GSI (0 if there's no PIC and IOAPIC) on x86.
And it thinks IRQ 0 is an architecture special IRQ, not for device driver. As a
result, the device driver may goes wrong if the allocated IRQ is 0 for RTVM.
This patch expose vIOAPIC to RTVM with LAPIC passthru even though the RTVM can't
use IOAPIC, it servers as a place holder to fullfil the guest assumption.
After vIOAPIC has exposed to guest unconditionally, the 'ready' field could be
removed since we do vIOAPIC initialization for each guest.
