v2 -> v3:
 - Keep only the root port base class code in pcie_root_port.c (Michael)
 - Use msix for the generic root port implementation (Michael and Gerd)
   - The task required some refactoring like having some common
     init/uninit interrupts functions to be implemented by both
     generic and Intel Root Ports.

v1 -> v2:
 - Rebased on master.

The Generic Root Port behaves the same as the
Intel's IOH device with id 3420, without having
Intel specific attributes.

The device has two purposes:
 (1) Can be used on both X86 and ARM machines.
 (2) It will allow us to tweak the behaviour
    (e.g add vendor-specific PCI capabilities)
     - something that obviously cannot be done
       on a known device.

Patch 1/3: Introduce a base class for Root Ports - most of the code
           is migrated from IOH3420 implementation.
Patch 2/3: Derives the IOH3420 from the new base class
Patch 3/3: Introduces the generic Root Port.

Tested with Linux and Windows guests only on x86 hosts.

(on aarch64, Fedora guest)

Much appreciated!
