I did grep and check the options, but it seems I missed this one.

Updated patch below.

There are two points:
- re-adding is trivial if it's ever needed, but until then it only
bloats the kernel
- drivers/ide/ are the legacy IDE drivers that will be superseded

This patch contains the following clenups:
- setup-pci.c: #if 0 the unused ide_pci_unregister_driver()
- ide-dma.c: remove the unused EXPORT_SYMBOL_GPL(ide_in_drive_list)
