ACPI: OSL: Poweroff when encountering a fatal ACPI error

The ACPI spec states that the operating system should respond
to a fatal ACPI error by "performing a controlled OS shutdown in
a timely fashion". Comply with the ACPI specification by powering
off the system when ACPICA signals a fatal ACPI error. Users can
still disable this behavior by using the acpi.poweroff_on_fatal
kernel option to work around firmware bugs.
