ALSA: usb-audio: Add QUIRK_FLAG_MIXER_{PLAYBACK,CAPTURE}_LINEAR_VOL
Some quirky devices tune their volume by linearly tuning the voltage
level (linear volume). In other words, such devices has a linear TLV
mapping of DECLARE_TLV_DB_LINEAR(scale, TLV_DB_GAIN_MUTE, 0).
Add quirk flags MIXER_PLAYBACK_LINEAR_VOL and MIXER_CAPTURE_LINEAR_VOL
to represent this case respectively for playback and capture mixers.
No functional change intended.
