attribute_group are not supposed to change at runtime. All functions
working with attribute_group 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
  28720     985      12   29717    7415 net/.../cxgb3/cxgb3_main.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  28848     857      12   29717    7415 net/.../cxgb3/cxgb3_main.o
