Subject: Moved, renamed, and deleted files

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

+ * struct of_dev_auxdata - lookup table entry for device names & platform_data
+ * @compatible: compatible value of node to match against node
+ * @phys_addr: Start address of registers to match against node
+ * @name: Name to assign for matching nodes
+ * @platform_data: platform_data to assign for matching nodes
+ *
+ * This lookup table allows the caller of of_platform_populate() to override
+ * the names of devices when creating devices from the device tree.  The table
+ * should be terminated with an empty entry.  It also allows the platform_data
+ * pointer to be set.
+ *
+ * The reason for this functionality is that some Linux infrastructure uses
+ * the device name to look up a specific device, but the Linux-specific names
+ * are not encoded into the device tree, so the kernel needs to provide specific
+ * values.
+ *
+ * Note: Using an auxdata lookup table should be considered a last resort when
+ * converting a platform to use the DT.  Normally the automatically generated
+ * device name will not matter, and drivers should obtain data from the device
+ * node instead of from an anonymouns platform_data pointer.
