ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify()
Since acpi_bus_notify() is executed on all notifications for all devices anyway, make it execute acpi_device_hotplug() for all hotplug events instead of installing notify handlers pointing to the same function for all hotplug devices. This change reduces both the size and complexity of ACPI-based device hotplug code. Moreover, since acpi_device_hotplug() only does significant things for devices that have either an ACPI scan handler, or a hotplug context with .eject() defined, and those devices had notify handlers pointing to acpi_hotplug_notify_cb() installed before anyway, this modification shouldn't change functionality.
