[PATCH 6/9] xen/ppc: address violations of MISRA C:2012 Rule 11.8.

[Simone Ballarin <simone.ballarin@bugseng.com>]

From: Maria Celeste Cesario <maria.celeste.cesario@bugseng.com>

The xen sources contain violations of MISRA C:2012 Rule 11.8 whose
headline states:
"A conversion shall not remove any const, volatile or _Atomic qualification
from the type pointed to by a pointer".

Fix violation by adding missing const qualifier in cast.
