        powerpc: update fadump sysfs node path
    
        The fadump sysfs nodes /sys/kernel/fadump_[enabled|registered], have
        been relocated to /sys/kernel/fadump/[enabled|registered] by kernel
        commits d418b19f34ed ("powerpc/fadump: Reorganize /sys/kernel/fadump_*
        sysfs files").
    
        To ensure compatibility, symbolic links were added for each relocated
        sysfs entry. Nonetheless, note that these symbolic links might be
        removed later, as they have been deprecated by kernel commit
        3f5f1f22ef10 ("Documentation/ABI: Mark /sys/kernel/fadump_* sysfs files
        deprecated")
    
        This patch updates the scripts to use the updated fadump sysfs files.
