[PATCH 13/18] ide: remove CONFIG_BLK_DEV_HD_IDE config option

[Bartlomiej Zolnierkiewicz]

* Remove CONFIG_BLK_DEV_HD hack from init_hwif_default() ("ide0=noprobe"
  kernel parameter should be used instead if somebody wishes to use the
  old "hd" driver).

* Make CONFIG_BLK_DEV_HD_ONLY config option available also when IDE
  subsystem is used and update help entry.

* Remove no longer needed CONFIG_BLK_DEV_HD_IDE config option.
