Add mixer quirk for Tascam US-16x08 usb interface.
Even that this an usb compliant device,
the input channels and DSP functions (EQ/Compressor)
arn't accessible by default.
In v3 I did changed the following:
exchange MUA to keep code style,
remove all globals,
all declaration static (where possible),
use standard snd_ctl_boolean_mono_info() when possible,
NULL check for all kmalloc(),
Remove redundant code,
add comments where needed,
fix macro arguments,
replace uint8_t with u8/s8,
remove all typedefs (if possible),
add resume callback.
