Some callers call this from __init code, which is OK.

Other callers call it from an inlined function and I'm too lazy to work
out if all the callers of those callers are calling
memblock_first_region_size() from a compatible section.

So please either a) demonstrate that all the sectioning is correct (and
maintainable!) or b) simply inline memblock_first_region_size()...
