If HOB contains APCI table information, entry point of AcpiTableDxe.inf
should parse the APCI table from HOB, and install these tables.
We assume the whole ACPI table (starting with EFI_ACPI_2_0_ROOT_SYSTEM_DESCRIPTION_POINTER)
is contained by a single gEfiAcpiTableGuid HOB.

MdeModulePkg\Universal\Acpi\AcpiTableDxe\AcpiTableDxe.inf is capable to install
ACPI table contained in HOB. All ACPI table shoulb be managed by that module.
