Turn ACPI and PCI devices off or to a lower power state in suspend and
back on again in resume. Override the default of D3 with the value the
BIOS specifies in _SxD, if present. Skip serial devices (PNP05xx) since
they seem to hang when set to D3 and may require special driver support.
Also, skip non-type 0 PCI devices (i.e., bridges) since our we don't yet
save/restore their config space and that seems to be necessary.
If this gives you trouble with suspend/resume, you can disable the new
ACPI and PCI power behavior separately with these tunables & sysctls:
debug.acpi.do_powerstate
hw.pci.do_powerstate
Approved by: imp (pci)
Tested by: acpi@ (numerous)
