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".
