dev, scheduler, ahci, dev: Refactor scheduler, and fix minor mistakes.
Add kDeviceTypeATA in DeviceMgr.h, making NeKernel aware that ATA
devices can exist too.
The scheduler now won't have to reimplement new classes, I refactor the
names to signal that, and they're already generic enough to signal that.
The AHCI-Generic driver got cleaned up of any irrelevant code, such as
aligning the newly allocated pointer.
