[PATCH] ALSA: usb-audio: Add native DSD support for Esoteric D-05X

[PATCH] ALSA: usb-audio: Add native DSD support for Esoteric D-05X

[Jussi Laako]

Adds VID:PID of Esoteric D-05X to the TEAC device id's.
Renames the is_teac_50X_dac() function to is_teac_dsd_dac() to cover
broader device family from the same corporation sharing the same USB
audio implementation.
