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.

I tested this both on x86/q35 (Debian guest) and on
aarch64/virt (Fedora guest) very briefly, eg. started
the guest, performed some network I/O and shut it down.

It seems to be working fine :)

Thanks for testing it! A tested-by tag would be appreciated for the next 
version :)
