I've build-tested on some failing platforms theses 2 patches and the
build are now succeeding. The only PM related zImage build error I found
was for s5pc100:

arch/arm/plat-samsung/pm.c:32:26: fatal error: mach/pm-core.h: No such file or directory

S5PC100 is a armv7 that's why it's still selected. I guess it will still
need some extra care unless the pm-core.h file is provided. One can try
use the same file as for s5pv210.h. I guess that it has probably not be
done because it was not working (I'm even wondering the differences
between s5pc100 and s5pv210 but this has nothing to do with our current
build troubles).
