[IA64-SGI] more sparse I/O accessor fixes

I forgot to add 'const volatile' to the I/O read/write functions in the last
patch, and also forgot to update the _relaxed variants.  This patch fixes
that by adding 'const volatile' to the sn2 specific read/write routines as
well as the ia64 machine vector wrappers.
