Add proper ACPI support

[9xbt]

I want to detect when the user presses the phisical power button on the PC and save unsaved progress to disk and then shut down and it seems like that feature is not implemented. Can Cosmos devs implement it? Thanks

Basic ACPI support already existed for a long time, however we need an ACPI interrupter and to handle the SCI.
