[PATCH 2/2] eal: adjust intrinsic type casts for CXX

[Tyler Retzlaff]

_mm_prefetch does not take a volatile qualified pointer, cast it away.
Additionally the pointer type should be char * not void * so adjust the
cast to match.

_mm_cldemote does not take a volatile qualified pointer, cast it away.
