    xen/arm: Remove __initdata and __init to enable CPU hotplug
    
    CPU up flow is currently used during the initial boot to start secondary
    CPUs. However, the same flow should be used for CPU hotplug, e.g. when
    hotplugging secondary CPUs within the resume procedure (resume from the
    suspend to RAM). Therefore, prefixes __initdata and __init had to be removed
    from few data structures and functions that are used within the cpu up flow.
