Kernel: Rewrite basically all current disk io stuff

This is a big commit that was kinda hard to split to smaller ones.

Essentially we now look at all the mass storage devices from PCI
and initialize (P)ATA devices. This doesn't provide any more functionality
but better abstractions and everything doesn't have to be on its old
default port that might be different for modern computers.
