ide: Kconfig face-lift

* 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").
