e59ffbf30e pcm: add new 32-bit DSD sample format 
Add the new DSD_U32_LE sample format to alsa-lib.

NB include/pcm.h and include/sound/asound.h are updated so a new sync with the
kernel headers is not needed

b9f58dcc6f pcm: 2nd round of pcm_misc DSD fixes 
Functions 'snd_pcm_format_silence_64' and 'snd_pcm_format_size' also need to be
able to handle the DSD smaple format.

Changes from v1:
- Correct silence pattern for DSD

87df9f3b7a pcm: Fix DSD formats userland usability 
Support for DSD sample formats has been added a while ago. This patch makes
those sample formats beter usable from userland (e.g. aplay).

[These implementation details have been forgotten in the previous DSD
 support patch -- tiwai]

8ed98db259 Make some static tables and strings constants. 
By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.

The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.
