ALSA: hda: 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.

File size before:
   text	   data	    bss	    dec	    hex	filename
    995	    608	      0	   1603	    643	sound/pci/hda/hda_sysfs.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   1035	    544	      0	   1579	    62b	sound/pci/hda/hda_sysfs.o
