[SPARC]: Update ide headers. WARNING: this is known broken, fixes coming from Jens Axboe. 

- Jens needs to seperate out the IN/OUT macros to seperate what accesses
are to the IDE_DATA register and the rest.  On big-endian platforms
the IDE_DATA register should be accessed in big-endian for it to all
work out correctly or at least be compatible with the behavior existing
before the IDE platform macro interface changes in 2.5.x
