to make sure the flash is in array mode whenever we're about to
reboot. This is especially useful to allow "soft" reboot to work
which consists of branching back into the bootloader.

Setting the slowport to 8-bit mode is something that ought to be
done in the IXP2000 generic code, not in the MTD map driver. See
the description for ARM patch 2493/1 for an explanation.
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=2493/1
Now that 2493/1 has been accepted and will be upstream soon, this
doesn't need to be done in the map driver anymore.
