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

Optimize the timer update routine to look up wall clock once instead of
checking the position of each stream at each timer update.

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.
