Kernel/Storage: Unify all ATA devices

Browse source 
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.
