[PATCH] ppc32: MPC834x BCSR_SIZE too small for use in a BAT.

[Kumar Gala]

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.
