usb: gadget: Kconfig: enable separate compilation of uac1/uac2 functions
uac1 and uac2 functions are available through the configfs interface and it should be possible to build them without building their legacy gadgets. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

+ This Audio function is compatible with USB Audio Class

+ This driver doesn't expect any real Audio codec to be present

+ application may choose to do whatever it wants with the data
+ received from the USB Host and choose to provide whatever it
