Remove undocumented and stale debug.acpi.do_powerstate tunable. It was

added with hw.pci.do_powerstate but the PCI version was splitted into two
separate tunables later and now this is completely stale.  To make it worse,
PCI devices enumerated in ACPI tree ignore this tunable as it is handled by
a function in acpi_pci.c instead.
