ALSA: emu10k1: minor E-MU naming fixups

- Fix mixer source port names. These will require some users to
  re-adjust their mixer settings, which seems acceptable:
  - The S/PDIF port is on the main 1010 card, not the 0202 daughter card
  - The 1616m CardBus card has all inputs on the dock, so there is
    no point in specifying it
  - Conversely, the 1010 card has "dispersed" inputs, so say where the
    ADAT port is, consistently with the S/PDIF port
- The 1616m CardBus card is actually named E-MU 02 (due to the headphone
  output jack it has)
- Fix capitalization of "E-MU"
