Introduced rte_prefetch_non_temporal() to remove IA specific _mm_prefect(addr, 0)
gcc intrinsic and build examples/distributor for non 86 platform

ping for review.

Is there much performance difference between making this a prefetch NT vs making
it an rte_prefetch0 on the platforms you have tested?

Not much difference. But, I think its worth keep the abstraction as
IA and arm64 architecture supports it.

Not sure the rte_prefetch_non_temporal mapping correct for
all the platforms. Architecture maintainers please check the mapping for
rte_prefetch_non_temporal() for specific architecures
