pm: acpi pm: add DMI quirk list for ACPI 1.0 suspend ordering 

There are a few BIOSes 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.
