Kernel: Introduce the new Storage subsystem

Browse source 
This new subsystem is somewhat replacing the IDE disk code we had with a
new flexible design.

StorageDevice is a generic class that represent a generic storage
device. It is meant that specific storage hardware will override the
interface. StorageController is a generic class that represent
a storage controller that can be found in a machine.

The IDEController class governs two IDEChannels. An IDEChannel is
responsible to manage the master & slave devices of the channel,
therefore an IDEChannel is an IRQHandler.
