ACPI: bugfix reporting of event handler status
Introduce a new flag showing whether the event has an event handler/method.
For all the GPEs and Fixed Events,
1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event.
2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set,
it's "disabled".
3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set,
it's "enabled".
4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set,
it's "wake_enabled".
Among other things, this prevents incorrect reporting of ACPI events
as being "invalid" when it's really just (temporarily) "disabled".
