- Added suspend/resume support.

- Added 4 speaker enable to initialization sequence.

- Removed delays between register pokes which appear to aggravate a
problem this card has sampling at 44.1kHz. With any form of delay,
skew relative to system clock at 44.1kHz is usually in range 0-25%
(now 0-3%). No other rates exhibit this problem.

- Changed structs cmi_* to sc_*.
