CTUAA should be checked instead of CTHENDRIX.  The latter is for 20k2 chip.
Also, fixed the detection of UAA/HENDRIX models by fixing the mask bits.

- Clean up Hungarian coding style
- Don't use static variables for I2C information; this unables to use
  multiple instances.  Now they are stored in struct hw20k2 fields.

- Use static tables instead of assigining each funciton pointer
- Add __devinit* to appropriate places; pcm, mixer and timer cannot be
  marked because they are kept in the function table that lives long

emu20k1 has a native timer interrupt based on the audio clock, which
is more accurate than the system timer (from the synchronization POV).
This patch adds the code to handle this with multiple streams.

The system timer is still used on emu20k2, and can be used also for
emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.

The device seems supporting only U8, S16, S24_3LE, S32.  Other linear

The prepare callback can be called multiple times, thus it needs to

Commit 360782dd (hwmon: (w83781d) Stop
abusing struct i2c_client for ISA devices) broke W83782D support for
devices connected on the ISA bus. You will hit a NULL pointer
dereference as soon as you read any device attribute. Other devices,
and W83782D devices on the SMBus, aren't affected.
