* 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.
v2:
* 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.
