[PATCH] acpi hotplug: decouple slot power state changes from physical hotplug

Current acpiphp code does not distinguish between the physical presence and
power state of a device/slot.  That is, if a device has to be disabled, it
also tries to physically ejects the device.  This patch decouples power state
from physical presence.  You can now echo to the corresponding sysfs power
control file to repeatedly enable and disable a device without having to
physically re-insert it.
