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.

- CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM
- and therefore can be supported by more hardware. Technically ECM and
- EEM are designed for different applications. The ECM model extends
- the network interface to the target (e.g. a USB cable modem), and the
- EEM model is for mobile devices to communicate with hosts using
- ethernet over USB. For Linux gadgets, however, the interface with

+ CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM
+ and therefore can be supported by more hardware. Technically ECM and
+ EEM are designed for different applications. The ECM model extends
+ the network interface to the target (e.g. a USB cable modem), and the
+ EEM model is for mobile devices to communicate with hosts using
+ ethernet over USB. For Linux gadgets, however, the interface with
+ the host is the same (a usbX device), so the differences are minimal.
