For some embedded devices, we need reduce code size and data footprint as much as possible, e.g. disabling procfs, hw/sw params refinement, mmap, dpcm, dapm, compressed API...

Here add SND_PROC_FS item for expert, we can unselect it to disable sound proc FS and reduce memory footprint.

There is SND_VERBOSE_PROCFS that also depends on PROC_FS. You should change it as well to depend on SND_PROC_FS.

OK, will change it also.
