    xen/arm/atomic: change parameter name in atomic_cmpxchg() definition
    
    Change parameter name from 'ptr' to 'v' in the function definition thus
    addressing violations of MISRA C:2012 Rule 8.3: "All declarations of an
    object or function shall use the same names and type qualifiers".
    
    No functional changes.
