ALSA: usb-audio: Add native DSD support for TEAC 501/503 DAC

This patch adds native DSD support for the following devices.

- TEAC NT-503
- TEAC UD-503
- TEAC UD-501

(1) Add quirks for native DSD support for TEAC devices.
(2) A specific vendor command is needed to switch between PCM/DOP and
    DSD mode, same as Denon/Marantz devices.
