    xen/arm: cpregs: Allow HSR_CPREG* to receive more than 1 parameter
    
    At the moment, HSR_CPREG is expected to receive only the co-processor
    register name in parameter. Because the name is actually a define, this
    may have been expanded by a previous macro.
    
    Rather than imposing the use of _HSR_CPREG* in such cases, allow
    HSR_CPREG to receive more than 1 parameter.
