* Add ->set_capacity block device method and use it in rescan_partitions()
to attempt enabling native capacity of the device upon detecting the
partition which exceeds device capacity.
* Add GENHD_FL_NATIVE_CAPACITY flag to try limit attempts of enabling
native capacity during partition scan.
Together with the consecutive patch implementing ->set_capacity method in
ide-gd device driver this allows automatic disabling of Host Protected Area
(HPA) if any partitions overlapping HPA are detected.
