Paolo Bonzini 6fdf98f281 fw_cfg: the I/O port variant expects little-endian 
The I/O port variant of fw_cfg is used by sparc64, which is a big-endian machine.
Firmware swaps bytes before sending them to fw_cfg, so we need to unswap them in
the device.

This is only used on sparc64 and on (little-endian) x86, so it does not affect
any other target.  32-bit Sparc and PPC all use memory-mapped fw_cfg.
