[PATCH v2] ALSA: usb-audio: Add iface reset and delay quirk for JKY Technology Q2A

[胡连勤]

Setting up the interface when suspended/resuming fails on this card.
Adding a reset and delay quirk will eliminate this problem.

Note: This device's VID conflicts with Apple's (0x05ac).

usb 1-1: New USB device found, idVendor=05ac, idProduct=110b
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1: Product: Q2A
usb 1-1: Manufacturer: JKY Technology
usb 1-1: SerialNumber: 330270D2251225
