powerpc allyesconfig fails like this:

drivers/video/fbdev/controlfb.c: In function 'controlfb_mmap':
drivers/video/fbdev/controlfb.c:756:23: error: implicit declaration of function 'pgprot_cached_wthru'; did you mean 'pgprot_cached'? [-Werror=implicit-function-declaration]
  756 |   vma->vm_page_prot = pgprot_cached_wthru(vma->vm_page_prot);
      |                       ^~~~~~~~~~~~~~~~~~~
      |                       pgprot_cached
drivers/video/fbdev/controlfb.c:756:23: error: incompatible types when assigning to type 'pgprot_t' {aka 'struct <anonymous>'} from type 'int'

Fix it by adding missing PPC32 dependency.
