eal/x86: fix prefetch with C++ for MSVC
_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.
Fixes: 28a5e0b9c7f0 ("eal/x86: implement prefetch for MSVC")
