usb: gadget: Gadget directory cleanup - group legacy gadgets

The drivers/usb/gadget directory contains many files.
Files which are related can be distributed into separate directories.
This patch moves the legacy gadgets (i.e. those not using configfs)
into a separate directory.

- * The Mass Storage Gadget acts as a USB Mass Storage device,
- * appearing to the host as a disk drive or as a CD-ROM drive.  In
- * addition to providing an example of a genuinely useful gadget
- * driver for a USB device, it also illustrates a technique of
- * double-buffering for increased throughput.  Last but not least, it
- * gives an easy way to probe the behavior of the Mass Storage drivers
- * in a USB host.
- *
- * Since this file serves only administrative purposes and all the
- * business logic is implemented in f_mass_storage.* file.  Read
- * comments in this file for more detailed description.
