ACPI, APEI, ERST debug support
This patch adds debugging/testing support to ERST. A misc device is implemented to export raw ERST read/write/clear etc operations to user space. With this patch, we can add ERST testing support to linuxfirmwarekit ISO (linuxfirmwarekit.org) to verify the kernel support and the firmware implementation.
