ide: remove CONFIG_BLK_DEV_HD_IDE config option (take 2)
* Remove CONFIG_BLK_DEV_HD hack from init_hwif_default()
("hda=noprobe hdb=noprobe" kernel parameters 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.
v2:
* Update documentation to suggest "hda=noprobe hdb=noprobe"
instead of obsoleted "ide0=noprobe".
* Update Documentation/ide/ide.txt.
