28599af387 Kernel: Allow to initialize an IDE device on the secondary channel 
We now use major number 3, and the minor number is set to 0 or 2 if
initialized on the primary channel, otherwise 1 or 3 on the secondary
channel.

0a2b00a1bf Kernel: Introduce the new Storage subsystem 
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.
