The problem is Linux registers pm_power_off = efi_power_off only if we are in hardware reduced mode. Actually, what we also want is to do this when ACPI S5 is simply not supported on non-legacy platforms. That should handle both the HW reduced mode, and the HW-full mode where the DSDT fails to supp
