Eric Wong 9fc88ad6fd ALSA: usb-audio: don't try to get Benchmark DAC1 sample rate 
Adding this quirk allows us to avoid the noisy
"cannot get freq at ep 0x1" message in dmesg output every time
playback starts.

This ought to affect other Benchmark DAC1 variations using the same
"Microchip Technology, Inc." chip as well, but I have only tested
with the "Pre" variant.
