ALSA: usb-audio: Add capture quirk for Behringer FCA1616
The Behringer FCA1616 (1397:0004) returns silent capture samples unless its
playback endpoint is active.
Use the existing fixed implicit-feedback mechanism to keep playback endpoint
0x01 on interface 1 active during capture.
Tested with 16-channel S32_LE capture at 44.1 and 48 kHz.
