vt8623fb: fix kernel oops

commit 20e061fb750d36ec0ffcb2e44ed7dafa9018223b
  Author: Ondrej Zajicek <santiago@crfreenet.org>

      fbdev: framebuffer_alloc() fixes

      Correct the dev arg of framebuffer_alloc() in arkfb, s3fb and vt8623fb.

causes a null-pointer deref because "info->dev is NULL, info was just
kzallocated".
