xen/efi: address violations of MISRA C:2012 Rule 11.8

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.
