    xen/arm: vgic: Clarify some comments after 5d495f4
    
    Ian pointed out that the definition of "offset" and "appropriate
    boundary" in the comments added by "xen/arm: vgic: Optimize the way to
    store the target vCPU in the rank" were not cleared.
    
    Clarify them by explicitly mentionning the offset is in byte and the
    appropriate boundary is ITARGET<n>/IROUTER<n>
