Wai Yew CHAY 29959a09cc ALSA: ctxfi - Add PM support
Added the suspend/resume support to ctxfi driver.

The team tested on the following seems ok:
  AMD Athlon 64 3500+ / ASUS A8N-E / 512MB DDR ATI / Radeon X1300
  20k1 & 20k2 cards

Takashi Iwai 09521d2e3e ALSA: ctxfi - Fix wrong model id for UAA
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.

Takashi Iwai 9470195a9c ALSA: ctxfi - Clean up probe routines
Clean up probe routines and model detection routines so that the driver
won't call and check the PCI subsystem id at each time.

Takashi Iwai 54de6bc8b2 ALSA: ctxfi - Optimize the native timer handling using wc counter
Optimize the timer update routine to look up wall clock once instead of
checking the position of each stream at each timer update.

Takashi Iwai 2a36f67f8c ALSA: ctxfi - Clean up / optimize
- 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

Takashi Iwai b7bbf87608 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.

Takashi Iwai 42a0b31827 ALSA: ctxfi - Fix endian-dependent codes
The UAA-mode check in hwct20k1.c is implemented with the endian-dependent
codes.  Fix to be more portable (and readable).

Takashi Iwai 6d74b86d3c ALSA: ctxfi - Allow 64bit DMA
emu20kx chips support 64bit address PTE.  Allow the DMA bit mask to
accept 64bit address, too.

Takashi Iwai cd391e206f 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.
