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?
