Assert that PCI devices discovered while booting the hypervisor do not
have more table entries than allowed by the compile-time configuration
(CONFIG_MAX_MSIX_TABLE_NUM).
The case were `msix.table_count` > `CONFIG_MAX_MSIX_TABLE_NUM` is fatal
since the init function in the handler for MSI-X (vmsix_init) only looks
at `table_count` when populating the table. Since
`CONFIG_MAX_MSIX_TABLE_NUM` is the max size of the table array entry in
the pci_msix struct. This will cause the msix handler to write outside of
the table array.

Except for few translation structures in x86 IOMMU, all translation
structures are 128-bit. All the translation structures used by ACRN
are 128 bit. So removed multiple definitions and defined a struct

In partition mode, unassign_iommu_device() is called from vpci_cleanup(),
so when shutdown_vm() is called, unassign_iommu_device() could fail because
of "domain id mismatch" and DMAR is not cleared.
Also move destroy_ept() after the call to destroy_iommu_domain().

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.
