[RFC PATCH 07/19] ide: remove deprecated delkin_cb host driver

[Bartlomiej Zolnierkiewicz]

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.

The replacement driver (pata_ninja32) has been available since
2007 and it supports all the hardware supported by the old
delkin_cb host driver.

Remove the deprecated delkin_cb host driver.

-/*
- *  Created 20 Oct 2004 by Mark Lord
- *
- *  Basic support for Delkin/ASKA/Workbit Cardbus CompactFlash adapter
- *
- *  Modeled after the 16-bit PCMCIA driver: ide-cs.c
- *
- *  This is slightly peculiar, in that it is a PCI driver,
- *  but is NOT an IDE PCI driver -- the IDE layer does not directly
- *  support hot insertion/removal of PCI interfaces, so this driver
- *  is unable to use the IDE PCI interfaces.  Instead, it uses the
- *  same interfaces as the ide-cs (PCMCIA) driver uses.
- *  On the plus side, the driver is also smaller/simpler this way.
- *
- *  This file is subject to the terms and conditions of the GNU General Public
- *  License.  See the file COPYING in the main directory of this archive for
- *  more details.

- * No chip documentation has yet been found,

- * a running Win98 system using "debug".
- * This gives around 3MByte/second read performance,
- * which is about 2/3 of what the chip is capable of.
- *
- * There is also a 4KByte mmio region on the card,
- * but its purpose has yet to be reverse-engineered.
