[PATCH 3/9] xen/efi: 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.
The variables are originally const-qualified.
There's no reason to drop the qualifiers.
