hwmon: constify attribute_group structures. 

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

File size before:
   text	   data	    bss	    dec	    hex	filename
   6655	    304	      0	   6959	   1b2f	drivers/hwmon/hwmon.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   6703	    240	      0	   6943	   1b1f	drivers/hwmon/hwmon.o
