[PATCH -mm 8/8] ACPI PM: Add DMI quirk list for ACPI 1.0 suspend ordering

["Rafael J. Wysocki" <rjw@sisk.pl>]

Subject: ACPI PM: Add DMI quirk list for ACPI 1.0 suspend ordering

There are a few BIOS' that we know of already that need to use the
ACPI 1.0 suspend order. This appears to be only be a small minority of
mostly nVidia based systems.

Based on observation of Windows behaviour, it's clear that Windows is
also doing maintaining its own list of broken hardware that needs this
workaround.
