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.
