ACPI: Expand SCI_EMULATE patch toward more generic usage.acpi-topic-arm64-apei
ACPI spec define that devices can be notified with some well
defined values. Handlers from system list are called for
notify values within 0-0x7F. In turn, handlers from device list
are called for notify value greater than 0x80. Till now only system
handler could be called. Now we are able to notify devices with all
notify values range that means we can emulate SCI line e.g. to trigger
APCI errors.
