Log:
[ACPI]
- Add support for fixed power buttons
- Cleanup some extra junk
- Add a hack to prevent acquiring the mutex while in an ISR or DPC
- Button events are received now and "acpi_bus_generate_event" will appear in
the debug log when a power/sleep button is pressed
- TODO: Implement IOCTL_GET_SYS_BUTTON_EVENT support so the power manager can recognize
our button presses
