platform_acpi_info.h should be BOARD specific so move the header file
to configs/$(CONFIG_BOARD)/ folder.
So the target acpi info file detect process is:
Compiler search for $(CONFIG_BOARD)_acpi_info.h under
hypervisor/arch/x86/$(CONFIG_BOARD)/ first (the file is supposed to be
generated by offline tool so it is not included in original source), if
found, then the file is the target acpi info file. If not and at the
same time the ENFORCE_VALIDATED_ACPI_INFO Kconfig was set, the compiler
will stop and hint user to add target acpi info file by offline tool.
If ENFORCE_VALIDATED_ACPI_INFO was unset, then compiler will continue to
search for platform_acpi_info.h as target acpi info file under
hypervisor/arch/x86/$(CONFIG_BOARD) folder (with this file we could bypass
ENFORCE_VALIDATED_ACPI_INFO check and benifit for development). If this
file is not exist, then hypervisor/arch/x86/configs/platform_acpi_info.h
will be included as final target acpi info.
The process should work for UEFI path also, with a valid platform acpi
info file, S3/S5 should work on UEFI platform.

get_dmar_info API is called from multiple functions in vtd.c. This patch
calls get_dmar_info once during init and uses the cached info during
runtime.

This patch is a modified one. It removes the usage
of acrn_vm struct from inside vtd.c.
It also puts struct iommu_domain inside vtd.h,
from vtd.c.
It modifies the signature of init_iommu_domain
in order to remove dependency on acrn_vm from
inside vtd.c.
Incorporated comments from Jason and Eddie.
Changed the name of sos_vm_domain to
fallback_iommu_domain
Removed any reference of sos_vm from vtd.[c|h]
files, including comments.

IOAPIC info from DMAR table is needed to match the IOAPIC info from
MADT. This patch adds support to get id and bus, devfn for IOAPIC
from DMAR. IOAPIC info for SBL platform is hardcoded in the header
file.
