ALSA: usb-audio: disable implicit feedback sync for Behringer UFX1204 and UFX1604
Behringer UFX1204 and UFX1604 have Synchronous endpoints to which current ALSA code applies implicit feedback sync as if they were Asynchronous endpoints. This breaks UAC compliance and is unneeded. The commit 5e35dc03 and subsequent 1a15718b were meant to clear up noise. Unfortunately, noise persisted for those using higher sample rates and this was only solved by commit d2e8f641 Since there are no more reports of noise, let's get rid of the implicit-fb quirks breaking UAC compliance.
