* 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.

- There are two drivers for MFM/RLL/IDE disks. Most people use just
