   [ide] fix via82cxxx resume failure

   With David Woodhouse <dwmw2@infradead.org>.

   On resume from sleep, via_set_speed() doesn't reinstate the correct
   mode, because it thinks the drive is already configured correctly.

   Also kill redundant printk, ide_config_drive_speed() warns about errors.

   [ide] kill ide-default

   * add ide_drives list to list devices without a driver
   * add __ide_add_setting() and use it for adding no auto remove entries
   * kill ide-default pseudo-driver

<bzolnier@trik.(none)> (05/04/02 1.2349)
   [ide] get driver from rq->rq_disk->private_data

   * add ide_driver_t * to device drivers objects
   * set it to point at driver's ide_driver_t
   * store address of this entry in disk->private_data
   * fix ide_{cd,disk,floppy,tape,scsi}_g accordingly
   * use rq->rq_disk->private_data instead of drive->driver
     to obtain driver (this allows us to kill ide-default)

   ide_dma_intr() OOPS fixed by Tejun Heo <htejun@gmail.com>.

<bzolnier@trik.(none)> (05/04/02 1.2348)
   [ide] kill ide_drive_t->disk

   * move ->disk from ide_drive_t to driver specific objects
   * make drivers allocate struct gendisk and setup rq->rq_disk
     (there is no need to do this for REQ_DRIVE_TASKFILE requests)
   * add ide_init_disk() helper and kill alloc_disks() in ide-probe.c
   * kill no longer needed ide_open() and ide_fops[] in ide.c

   ide_init_disk() fixed by Andrew Morton <akpm@osdl.org>.

<bzolnier@trik.(none)> (05/04/02 1.2347)
   [ide] add ide_{un}register_region()

   Add ide_{un}register_region() and fix ide-{tape,scsi}.c to register
   block device number ranges.  In ata_probe() only probe for modules.

   Behavior is unchanged because:
   * if driver is already loaded and attached to drive ata_probe()
     is not called et all
   * if driver is loaded by ata_probe() it will register new number range
     for a drive and this range will be found by kobj_lookup()

   If this is not clear please read http://lwn.net/Articles/25711/
   and see drivers/base/map.c.

   This patch makes it possible to move drive->disk allocation from
   ide-probe.c to device drivers.

   [ide] destroy_proc_ide_device() cleanup

   When this function is called device is already unbinded from a
   driver so there are no driver /proc entries to remove.

   [ide] drive->dsc_overlap fix

   drive->dsc_overlap is supported only by ide-{cd,tape} drivers.
   Add missing clearing of ->dsc_overlap to ide_{cd,tape}_release()
   and move ->dsc_overlap setup from ide_register_subdriver() to
   ide_cdrom_setup() (ide-tape enables it unconditionally).

   [ide] drive->nice1 fix

   It is drive's property independent of the driver being used so move
   drive->nice1 setup from ide_register_subdriver() to probe_hwif() in
   ide-probe.c.  As a result changing a driver which controls the drive
   no longer affects this flag.
