Subject[PATCH 13/18] ide: remove CONFIG_BLK_DEV_HD_IDE config option
* 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
- the new enhanced driver by itself. This option however installs the
- old hard disk driver to control the primary IDE/disk interface in
- the system, leaving the new enhanced IDE driver to take care of only
- the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
- having an IDE/ATAPI CD-ROM or tape drive connected to the primary
- IDE interface. Choosing this option may be useful for older systems
- which have MFM/RLL/ESDI controller+drives at the primary port
- address (0x1f0), along with IDE drives at the secondary/3rd/4th port
- addresses.
- Normally, just say N here; you will then use the new driver for all
