usb: gadget: f_uac1: convert to new function interface with backward compatibility
Converting uac1 to the new function interface requires converting
the USB uac1's function code and its users.
This patch converts the f_uac1.c to the new function interface.
The file is now compiled into a separate usb_f_uac1.ko module.
The old function interface is provided by means of a preprocessor
conditional directives. After all users are converted, the old interface
can be removed.
