* src/flashiodev.c (flashiodev_lookup): Moved most of the
flashiodev_init into this new function. This fixed the ordering
issue with redboot startup. When doing a FIS name lookup in
flashiodev_init, redboot was not yet initialized so lookup
failed. Moving this into flashiodev_lookup solves this problem.
Its now possible for redboot to mount the jffs2 filesystem with
-d /dev/flash1.
