[PATCH 5/9] xen/x86: address violations of MISRA C:2012 Rule 11.8

[Simone Ballarin <simone.ballarin@xxxxxxxxxxx>]

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

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".

Add missing const qualifiers in casts.

Macro get_mb2_data returns values that are const-qualified.
The results are stored in const struct pointers, hence
there's no need to cast away the const qualifiers.
