ACPI / scan: Make container driver use struct acpi_scan_handler
Make the ACPI container driver use struct acpi_scan_handler for representing the object used to initialize ACPI containers and remove the ACPI driver structure used previously and the data structures created by it, since in fact they were not used for any purpose. This simplifies the code and reduces the kernel's memory footprint by avoiding the registration of a struct device_driver object with the driver core and creation of its sysfs directory which is unnecessary. In addition to that, make the namespace walk callback used for installing the notify handlers for ACPI containers more straightforward. This change includes fixes from Toshi Kani.
