ALSA: usb-audio: Add implicit_fb module option
A new module option, implicit_fb, is added to specify the driver looking for the implicit feedback sync. This can be useful for a device that could be working better in the implicit feed back mode and user wants to test it quickly. When this works, we can add the quirk entry easily.
