arch/s390: clean up hugetlb definitions
s390 redefines functions that are already defined (and the same) in include/asm-generic/hugetlb.h. Do as the other architectures: 1) include include/asm-generic/hugetlb.h 2) drop the already defined functions in the generic hugetlb.h and 3) use the __HAVE_ARCH_HUGE_* macros to define our own. This gets rid of quite some code.
