DynamicTablesPkg: Arm ACPI MADT Generator
The MADT generator uses the configuration manager protocol to
obtain information about the Arm interrupt controllers (GICC,
GICD, etc.) and generates the ACPI MADT table. This table data
is then used by the Table Manager to install the MADT table.
The Table Manager then invokes the generator interface to free
any resources allocated by the MADT table generator.
