Kernel: Replace IRQHandler with the new InterruptHandler class

Browse source 
System components that need an IRQ handling are now inheriting the
InterruptHandler class.

In addition to that, the initialization process of PATAChannel was
changed to fit the changes.
PATAChannel, E1000NetworkAdapter and RTL8139NetworkAdapter are now
inheriting from PCI::Device instead of InterruptHandler directly.
