Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+ * vector map, or dynamic in the case of board mux vectors or MSI.
+ *
+ * As this is a central point for all IRQ controllers on the system,
+ * each of the available sources are mapped out here. This combined with
+ * sparseirq makes it quite trivial to keep the vector map tightly packed
+ * when dynamically creating IRQs, as well as tying in to otherwise
+ * unused irq_desc positions in the sparse array.
