ia64: io: implement dummy relaxed accessor macros for writes
write{b,w,l,q}_relaxed are implemented by some architectures in order to
permit memory-mapped I/O accesses with weaker barrier semantics than the
non-relaxed variants.
This patch adds dummy macros for the write accessors to ia64, which may
be able to be optimised in a similar manner to the relaxed read
accessors at a later date.
