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
    3614            545    1560    5719    1657 x86/kernel/cpu/microcode/core.o

File size After adding 'const':
    text           data     bss     dec     hex filename
    3742            417    1560    5719    1657 x86/kernel/cpu/microcode/core.o

Again, what are those before/after sizes supposed to show?

It's just show, how much bytes move from data segment to text segment.
