ALSA: ctxfi - Use native timer interrupt on emu20k1
...
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.

ALSA: ctxfi - Remove PAGE_SIZE limitation
...
Remove the limitation of PAGE_SIZE to be 4k by defining the own
page size and macros for 4k. 8kb page size could be natively supported,
but it's disabled right now for simplicity.
Also, clean up using upper_32_bits() macro.

ALSA: ctxfi - Fix supported PCM formats
...
The device seems supporting only U8, S16, S24_3LE, S32. Other linear
formats result in bad outputs.
Also, added the support for 32bit float format, which wasn't listed

ALSA: ALSA: ctxfi - Release PCM resources at each prepare call
...
The prepare callback can be called multiple times, thus it needs to
release and acquire the resource again by itself at the second or later
call.
Simply add pcm_release_resources() at the beginning of each prepare
callback in ctatc.c.
