ALSA: pcm: constify attribute_group structures. 

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/device.h> work with const
attribute_group. So mark the non-const structs as const.

   text	   data	    bss	    dec	    hex	filename
   9781	    240	      8	  10029	   272d	sound/core/pcm.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   9813	    176	      8	   9997	   270d	sound/core/pcm.o
