ACPI Hardware Error Device (PNP0C33) support
Hardware Error Device (PNP0C33) is used to report some hardware errors notified via SCI, mainly the corrected errors. Some APEI Generic Hardware Error Source (GHES) may use SCI on hardware error device to notify hardware error to kernel. After receiving notification from ACPI core, it is forwarded to all listeners via a notifier chain. The listener such as APEI GHES should check corresponding error source for new events when notified.
