Fredrik Holmqvist 01f964efeb Introduce a gSystemShutdown flag to be able to check if system is shutting down. ACPI Embedded Controller now uses polling when it is set to true.
This might help with ACPI shutdown issues, if not this change can be reverted. Not verified as it works on all my machines even without this.
