ide: add ide_transfer_pc() helper
* Add ide-atapi.c file for generic ATAPI support together with
CONFIG_IDE_ATAPI config option.
* Add generic ide_transfer_pc() helper to ide-atapi.c and then
convert ide-{floppy,tape,scsi} device drivers to use it.
There should be no functional changes caused by this patch.
