[PATCH] Allow small areas in io_block_mapping

The attached patch stops io_block_mapping() from attempting to use BATs
for areas too small to fit in a BAT.  (On the port I'm currently
developing, the board uses high-order address lines to distinguish
between register groups, and I'm trying to allocate a page for each group.)
