Fix up SPDIF input sample rates again: 32 kHz and 64 kHz are not
supported.

Add one more indirection to the lookup of the snd_pcm_hardware
structures so that we can save the space of the duplicate ones.

Change the oxygen_spdif_input_bits_changed() function so that clock
changes on the SPDIF input are correctly detected. This means that
sample rates greater than 96 kHz are now supported.

Add proper register bit symbols for the I2S format field, and allow card
models to configure the I2S format to be used for the DACs and ADCs.

Use an array for the pointers to known controls so that it is easier to

This header file exists only for some hacks to adapt alsa-driver
tree. It's useless for building in the kernel. Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it. This should be really killed in
future.

When we store the DMA channel number in the substream's private_data
pointer, use uintptr_t as an intermediate step when casting from/to
unsigned int to prevent the compiler from whining when the pointer size
is different.

Add the snd-oxygen driver for the C-Media CMI8788 (Oxygen) chip, used on
the Asound A-8788, AuzenTech X-Meridian, Bgears b-Enspirer,
Club3D Theatron DTS, HT-Omega Claro, Razer Barracuda AC-1,
Sondigo Inferno, and TempoTec HIFIER sound cards.
