fbdev: move logo externs to header file

Now we have __initconst, we can finally move the external declarations for
the various Linux logo structures to <linux/linux_logo.h>.

James' ack dates back to the previous submission (way to long ago), when the
logos were still __initdata, which caused failures on some platforms with some
toolchain versions.
