ACPICA: Re-implement interpreters' "serialized mode"
Enhanced the implementation of the interpreters' serialized mode (boot with "acpi_serialize" to set acpi_glb_all_methods_serialized flag.) When this mode is specified, instead of creating a serialization semaphore per control method, the interpreter lock is simply no longer released before a blocking operation during control method execution. This effectively makes the AML Interpreter single-threaded. The overhead of a semaphore per-method is eliminated.
