[PATCH] ppc32: Fix a warning in planb video driver

[Tom Rini <trini@kernel.crashing.org>]

[ aside: This has been sitting in the linuxppc-2.5 bk tree for I don't
  know how long.  And the driver is still horribly broken. ]

The following patch moves overlay_is_active to before its first use.  It
was originally written when gcc wouldn't complain, but now does, about
not having the definition before usage.
