Andrzej Pietrasiewicz dc8c46a5ae usb: gadget: f_tcm: convert to new function interface with backward compatibility
Converting tcm to the new function interface requires converting
USB tcm's function code and its users.

This patch converts the f_tcm.c to the new function interface.

The file can be now compiled into a separate module usb_f_tcm.ko.

The old function interface is provided by means of preprocessor conditional
directives. After all users are converted, the old interface can be
removed.
