Changes:

• Building the BIOS Drive Information Tool now works again.
• Moved all XT-CF related code to MODULE_8BIT_IDE_ADVANCED. I don't see how an XT-CF card could work without *_ADVANCED anyway but if I'm wrong, feel free to undo this. Note! The autodetection code in XTIDECFG has NOT been changed to reflect this (still relies on MODULE_8BIT_IDE).
• Optimizations and fixes in general.
