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

From: Jussi Laako <[email protected]>

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.
