There's basically no real difference in software between a SATA harddisk and IDE harddisk. The difference in the implementation is for the host bus adapter protocol and registers layout. Therefore, there's no point in putting a distinction in software to these devices. This change also greatly simplifies and removes stale APIs and removes unnecessary parameters in constructor calls, which tighten things further everywhere.
