Well, for TX493x (MIPS), we have CONFIG_SWAP_IO_SPACE for big endian
and it works fine for PCI-IDE host controllers. For SoC internal
controllers, no swapping is needed for both endian, thus custom tp_ops
is needed only for big endian.

So ... IDE_BE_IO looks actually not best name for this case. It is
IDE_RAW_IO or something. But IDE_RAW_IO might not fit for other
cases. IDE_SWAPPED_IO? Any other good name?
