/** @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.
