Try to take small steps then: See if there is something in this code
that is either never called, or data structures that are only
written but never read, or pointers that are verifiably always 
NULL, then eliminate one piece of the code at a time, with a patch
that explains what you found.

Try to make sure everything still builds after each patch, and note
that this was not the case with your first patch, though it would have
worked in the reverse order.

I suspect the best way forward is to actually move all of
ab8500_regulator_plat_data and whatever it references into
drivers/regulator/ab8500-ext.c because there now is only one
remaining instance of that. After this move, you can delete
a lot of code in arch/arm/mach-ux500 and possibly move all of
include/linux/regulator/ab8500.h into drivers/regulator/ab8500-ext.c
as well.
