Input: yealink - 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
   6039	    944	      0	   6983	   1b47	drivers/input/misc/yealink.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   6103	    880	      0	   6983	   1b47	drivers/input/misc/yealink.o
