In order to suppose platforms with devices above 4Gb on 32 bits platforms
with a >32 bits physical address space, we used to have a special ioremap64
along with a fixup routine fixup_bigphys_addr.

This shouldn't be necessary anymore as struct resource now supports 64 bits
addresses even on 32 bits archs. This patch enables that option when
CONFIG_PHYS_64BIT is set and removes ioremap64 and fixup_bigphys_addr.

This is a preliminary work for the upcoming merge of 32 and 64 bits io.h

Rename mpc85xx.c to misc.c to match the pattern established by the
8349 port - consistency is a good thing.  Also run Lindent on the
file to clean it up.

Updated patch for support for mpc8540_ads in arch/powerpc with a
flat OF device tree. This patch does not yet support PCI or I2C.
