ALSA: usb-audio: Add clock validity quirk for Denon MC7000/MCX8000
commit 9f35a31283775e6f6af73fb2c95c686a4c0acac7 upstream.
It should be safe to ignore clock validity check result if the following
conditions are met:
- only one single sample rate is supported;
- the terminal is directly connected to the clock source;
- the clock type is internal.
This is to deal with some Denon DJ controllers that always reports that
clock is invalid.
