    * Use ->probed_capacity to store native device capacity for ATA disks.
    * Add ->set_capacity method to struct ide_disk_ops.
    * Implement disk device ->set_capacity method for ATA disks.
    * Implement block device ->set_capacity method.
    * Check if LBA and HPA are supported in ide_disk_set_capacity().
    * According to the spec the SET MAX ADDRESS command shall be
      immediately preceded by a READ NATIVE MAX ADDRESS command.
    * Add ide_disk_hpa_{get_native,set}_capacity() helpers.
    Together with the previous patch adding ->set_capacity block device
    method this allows automatic disabling of Host Protected Area (HPA)
    if any partitions overlapping HPA are detected.
