* Convert config options for PCI host drivers to select BLK_DEV_IDEPCI.

* Same for BLK_DEV_IDEDMA_PCI and PCI DMA host drivers, also make this
  config option select BLK_DEV_IDEPCI.

* Remove no longer needed help for BLK_DEV_IDEPCI and BLK_DEV_IDEDMA_PCI.

* Remove redundant IDE_CHIPSETS config option.

As a result of this patch users have now three less config options
to worry about and can just select host drivers that they need
(IDE config menu is "flatter").

---help---
If your PCI system uses IDE drive(s) (as opposed to SCSI, say) and
is capable of bus-master DMA operation (most Pentium PCI systems),
you will want to say Y here to reduce CPU overhead. You can then use
the "hdparm" utility to enable DMA for drives for which it was not
enabled automatically. By default, DMA is not enabled automatically
for these drives, but you can change that by saying Y to the
following question "Use DMA by default when available". You can get
the latest version of the hdparm utility from
<ftp://ibiblio.org/pub/Linux/system/hardware/>.

Read the comments at the beginning of <file:drivers/ide/ide-dma.c>
and the file <file:Documentation/ide.txt> for more information.

It is safe to say Y to this question.

Say Y here if you want to include enhanced support for various IDE
interface chipsets used on motherboards and add-on cards. You can
then pick your particular IDE chip from among the following options.
This enhanced support may be necessary for Linux to be able to
access the 3rd/4th drives in some systems. It may also enable
setting of higher speed I/O rates to improve system performance with
these chipsets. Most of these also require special kernel boot
parameters to actually turn on the support at runtime; you can find
a list of these in the file <file:Documentation/ide.txt>.

People with SCSI-only systems can say N here.
