* Differentiate between bay devices in dock stations and others:
- When an ACPI_NOTIFY_EJECT_REQUEST appears, just signal uevent to
userspace (that is when the optional eject button on a bay device is
pressed/pulled) giving the possibility to unmount file systems and to
clean up. Also, only send uevent in case we get an EJECT_REQUEST
without doing anything else. In other cases, you'll get an add/remove
event because libata attaches/detaches the device.
- In case of a dock event, which in turn signals an
ACPI_NOTIFY_EJECT_REQUEST, immediately detach the device, because it
may already have been gone
* In case of an ACPI_NOTIFY_DEVICE/BUS_CHECK, evaluate _STA to check if
the device has been plugged or unplugged. If plugged, hotplug it, if
unplugged, just signal event to userspace

* Call ACPI _EJ0 for detached devices
