ACPI Hardware Error Device (PNP0C33) support

Browse source 
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.
