ALSA: usb-audio: Apply the control quirk to Plantronics headsets

Browse Source 
commit 06abcb18b3a021ba1a3f2020cbefb3ed04e59e72 upstream.

Other Plantronics headset models seem requiring the same workaround as
C320-M to add the 20ms delay for the control messages, too.  Apply the
workaround generically for devices with the vendor ID 0x047f.

Note that the problem didn't surface before 5.11 just with luck.
Since 5.11 got a big code rewrite about the stream handling, the
parameter setup procedure has changed, and this seemed triggering the
problem more often.
