c4463cb5df Kernel: Add basic AHCI functionality 
The hierarchy is AHCIController, AHCIPortHandler, AHCIPort and
SATADiskDevice. Each AHCIController has at least one AHCIPortHandler.

An AHCIPortHandler is an interrupt handler that takes care of
enumeration of handled AHCI ports when an interrupt occurs. Each
AHCIPort takes care of one SATADiskDevice, and later on we can add
support for Port multiplier.

When we implement support of Message signalled interrupts, we can spawn
many AHCIPortHandlers, and allow each one of them to be responsible for
a set of AHCIPorts.
