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
  11605     880      20   12505    30d9 drivers/media/rc/rc-main.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  11797     720      20   12537    30f9 drivers/media/rc/rc-main.o
