acpi/generic_event_device: add an APEI error device
Adds a generic error device to handle generic hardware error
events as specified at ACPI 6.5 specification at 18.3.2.7.2:
https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#event-notification-for-generic-error-sources
using HID PNP0C33.

The PNP0C33 device is used to report hardware errors to
the guest via ACPI APEI Generic Hardware Error Source (GHES).
