ACPI: Add D3 cold state
_SxW returns an Integer containing the lowest D-state supported in state
Sx. If OSPM has not indicated that it supports _PR3, then the value “3”
corresponds to D3. If it has indicated _PR3 support, the value “3”
represents D3hot and the value “4” represents D3cold.
Linux does set _OSC._PR3, so we should fix it to expect that _SxW can
return 4.
