[PATCH] input: synaptics-rmi4: Constify attribute_group structures.

[Arvind Yadav]

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
   4777	    480	      0	   5257	   1489	drivers/input/rmi4/rmi_f01.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   4817	    416	      0	   5233	   1471	drivers/input/rmi4/rmi_f01.o
