s390: Stop using weak symbols for __iowrite64_copy()
Complete switching the __iowriteXX_copy() routines over to use #define and arch provided inline/macro functions instead of weak symbols. S390 has an implementation that simply calls another memcpy function. Inline this so the callers don't have to do two jumps.
