Log Message:
acpi(9): Fix memory ordering and completion bugs in notifiers.

1. Guarantee everything which happened before acpi_register_notify
   has also happened before the notifier is actually called.

2. On acpi_deregister_notify, don't return until the notifier is
   definitely not running any more on any CPU, using
   AcpiOsWaitEventsComplete.
