    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.
