Liav A 72b144e9e9 Kernel/Graphics: Introduce a new mechanism to initialize a PCI device
Instead of using a clunky switch-case paradigm, we now have all drivers
being declaring two methods for their adapter class - create and probe.
These methods are linked in each PCIGraphicsDriverInitializer structure,
in a new s_initializers static list of them.
Then, when we probe for a PCI device, we use each probe method and if
there's a match, then the corresponding create method is called.

As a result of this change, it's much more easy to add more drivers and
the initialization code is more readable.
