ALSA: usb-audio - Added functionality for E-mu 0404USB/0202USB/TrackerPre
Added functionality:
1) Extension Units support (all XU settings now available at alsamixer,
kmix, etc):
- "AnalogueIn soft limiter" switch;
- "Sample rate" selector (values 0,1,2,3,4,5 corresponds to 44.1 48 ...
192 kHz);
- "DigitalIn CLK source" selector (internal/external) (**);
- "DigitalOut format SPDIF/AC3" switch (**);
(**)E-mu-0404usb only.
2) Automatic device sample rate adjustment depending on substream
samplerate for both capture and playback substream.
