Clean up probe routines and model detection routines so that the driver
won't call and check the PCI subsystem id at each time.

- 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
- Move create_alsa_devs function out of struct ct_atc to mark it
__devinit

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.

PCM names for surround streams should be also fixed as well as the mixer
element names. Also, a bit clean up for PCM name setup.
