[U-Boot] [RFC] Centralise documentation of CONFIG_ options (and finding unused ones)

I would tend to answer 'yes'. Unused options should not clobber code or 
documentation.

That would be nice indeed, but it requires all options to have the same 
semantics over all arches. While this is highly desirable, it may not be 
true ATM -- just thinking out loud, haven't checked. But even if some 
options only make sense only for some arch(es), then we could always do 
it this way:

	doc/README.CONFIG_options
	doc/README.CONFIG_SYS_options
	doc/arch/README.CONFIG_options
