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 v2:

• fix and simplify switch statement

Changes from v1:

• use specific product id and alt setting per XMOS based device

Signed-off-by: Jurgen Kramer gtmkramer@xs4all.nl

Applied with a minor coding style fix. At the next time, please run scripts/checkpatch.pl before the submission.

Also, don't forget to put maintainers to Cc, and align the subject line with the other commits for the target code.

thanks,

Takashi
