This change re-factors the device structure in parse tree to be able to support multidev devices just like non-multidev devices. With this change, every device has a bus under it which is the parent of all devices that fall on the bus. If there are duplicate entries in the devicetree, then there will be multiple buses under the device and each bus will have its own set of children. The tree starts out with a root device which has a root bus under it. This is a special device which is created statically and its parent is its own root bus. When parsing the device tree file, devices get added under the root bus as children. Since this change re-organizes the way devicetree is represented, it gets rid of latestchild and next_sibling pointers from struct device. Also, the tree traversal to generate static.c is changed to breadth-first walk instead of using the next_sibling. BUG=b:80081934 TEST=Verified using abuild that all boards compile successfully.
