drm/sti: restore mode_fixup callback

Commit 8a2fa38fddd3 removed the mode_fixup because it was empty,
but 652353e6e561 modified it to call drm_mode_set_crtcinfo()
instead.

Both commits are correct, but the merge of the two kept the nonempty
version without the reference to it, as shown by the gcc warning:

 drm/sti/sti_crtc.c:54:13: error: 'sti_crtc_mode_fixup' defined but not used

This restores the callback pointer to fix the merge.
