Ben Dooks 45c79433c0 ARM: S5PC100: Fixup merge problems
Between problems with Kconfig and merging commits from several
different sources, it seems the s5pc100 build's move from plat-s5pc11
has had a few problems.

Since I do not have the trees to rebuild this quickly, the easiest
thing is to simply fix the errors found once the s5pc100_defconfig
actually builds.
