Add quirks for XMOS based DACs for native DSD playback support using the new DSD_U32_LE sample format.
This version adds native DSD support for:
- iFi Audio micro iDSD/nano iDSD (they use the same prod. id)
- DIYINHK USB to I2S/DSD converter
Changes from v1:
- use specific product id and alt setting per XMOS based device

It is already returning. Where would the break go?
