[PATCH] x86_64: Clean up and tweak ACPI blacklist year code
- Move the core parser into dmi_scan.c. It can be useful for other
subsystems too.
- Differentiate between field doesn't exist and field is 0 or
unparseable. The first case is likely an old BIOS with broken ACPI,
the later is likely a slightly buggy BIOS where someone forget to
edit the date. Don't blacklist in the later case.
