    xen/arm: smmuv3: fix violations of MISRA C:2012 Rule 3.1
    
    In the file `xen/drivers/passthrough/arm/smmu-v3.c' there are a few 
occurrences
    of nested '//' character sequences inside C-style comment blocks, which 
violate
    Rule 3.1.
    
    The patch aims to resolve those by replacing the nested comments with
    equivalent constructs that do not violate the rule.
