Modified Files:
        src/sys/dev/acpi: acpi.c acpi_wakedev.c acpi_wakedev.h

Log Message:
Revisit the wake-device code once more.

  1. Remove the AcpiEnableGpe() call. This was wrong.

  2. Only call _PSW or _DSW for devices that are scheduled for wake.
     This was an old bug.

  3. Only enable wake GPEs during suspend. Disabling these for
     devices not setup for wake was causing problems.

  4. No wake GPEs should be enabled at runtime.
     Unconditionally disable these during resume.

This should make the wake-device code work again. Note that waking via
pckbd(4) has always been unreliable; the _PRW object is not typically located
under the PC keyboard object, but in the parent of it (e.g. the LPC bridge).
