acpi_bus_scan() currently walks the namespace manually. This patch changes it to use acpi_walk_namespace() instead. Besides removing some complicated code, this means we take advantage of the namespace locking done by acpi_walk_namespace(). The locking isn't so important at boot-time, but I hope to eventually use this same path to handle hot-addition of devices, when it will be important. Note that acpi_walk_namespace() does not actually visit the starting node first, so we need to do that by hand first.
