ide: add ide_device_{get,put}() helpers
* Add 'struct ide_host *host' field to ide_hwif_t and set it in ide_host_alloc_all(). * Add ide_device_{get,put}() helpers loosely based on SCSI's scsi_device_{get,put}() ones. * Convert IDE device drivers to use ide_device_{get,put}(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
