[PATCH] ppc32: MPC834x BCSR_SIZE too small for use in a BAT.
The call to io_block_mapping was creating an invalid BAT entry because the
value of BCSR_SIZE (32K) is too small to be used in a BAT (128K min). This
change removes the io_block_mapping call since these registers can easily
be mapped using ioremap at the point of use.
