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. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
