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

commit 866f7ed7d67936dcdbcddc111c8af878c918fe7c upstream.

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.
