Oswald Buddenhagen 6d68d9cba1 ALSA: emu10k1: rework copyright statements 
- Remove the "log-like" parts, following the same logic as the previous
  commit
- Unify format
- Add missing major contributors, including myself
- Sort entries in order of first contribution (Creative comes last for
  optical reasons; they don't appear to have directly contributed
  anyway)
