Simplify f_uac2 by removing platform driver/device
creation; use composite's usb_gadget device as
parent for sound card and for debug prints.
This removes extra layer of code without any functional
change.

- renamed u_audio exported symbols so they don't
conflict with old f_uac1 if both are built-in.
v2 changes:
- do not touch f_uac1, instead created f_uac1_newapi
- added documentation for f_uac1_newapi
- rebased on top of v4.8-rc
