drm_framebuffer_funcs are not supposed to change at runtime. So mark
the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   4002	    184	      0	   4186	   105a drivers/gpu/drm/drm_fb_cma_helper.o
