This patch converts the ISA MMIO bridge code to always use little endian mmio.
All bswap code that existed was only there to convert from native cpu
endianness to little endian ISA devices.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.
