Improve ACPI hotplug handling such that dock event is handled properly. * Register handlers for dock events. * Directly detach device on EJECT_REQUEST instead of signaling hotplug event. This prevents libata from accessing severed controller and/or device. * While at it, use named constants for ACPI events and move uevent signaling inside host lock. Original patch and testing by Holger Macht.
