ALSA: emu10k1: vastly improve usefulness of info in /proc

- Include the FX bus map, without which the already present send routing
  info would require looking up the documentation.
- Include the physical I/O channels as known to the driver
- Make the multi-channel capture map actually name the mapped input
  channels rather than "FXBUS" (Audigy) or even "???" (SbLive)
- The latter two are omitted for E-MU cards, as their physical I/O is
  routed through the FPGA
- While at it, make the "Card" field somewhat more useful

This includes de-duplicating the label tables between emuproc and emufx,
updating/improving the FX bus label table, and making the SB Live! 5.1
multi-track capture channel mapping hack data-driven.
