    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").
