/** @file
Default (stub) arch-specific ACPI MSCT Generator implementation.
Used for architectures that do not provide processor or clock domain
information via the Configuration Manager (e.g. RISCV64, LOONGARCH64).
Both functions return EFI_NOT_FOUND so that the common generator
gracefully omits the arch-specific topology data from the MSCT.
