Changes:

• Renamed MODULE_FEATURE_SETS to MODULE_POWER_MANAGEMENT.
• Renamed MODULE_VERY_LATE_INITIALIZATION to MODULE_VERY_LATE_INIT and removed it from the official builds.
• Removed the code that skips detection of slave drives on XT-CF controllers since slave drives can be used with Lo-tech ISA CompactFlash boards.
• Added autodetection of the SVC ADP50L controller to XTIDECFG.
• The autodetection of XT-CF controllers now requires MODULE_8BIT_IDE_ADVANCED in the loaded BIOS.
• Fixed a bug in XTIDECFG from r502 where the "Base (cmd block) address" menu option would be displayed when a serial device was selected as the IDE controller.
• XTIDECFG would display the "Enable interrupt" menu option for the XTIDE r1 but not for the XTIDE r2. It's now displayed for both controller types.
• Disabled the "Internal Write Cache" menu option in the Master/Slave Drive menus for serial device type drives.
• Optimizations and other fixes.
