Input: synaptics-rmi4 - constify attribute_group structures in F34

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
   5287	    448	      0	   5735	   1667	drivers/input/rmi4/rmi_f34.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   5339	    384	      0	   5723	   165b	drivers/input/rmi4/rmi_f34.o
