This change implements the VIRTIO_DEVICE_PROTOCOL for the PCI transport layer. The VirtIo device drivers will interact with the PCI-based VirtIo devices through this protocol implementation. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Olivier Martin <olivier.martin@arm.com> v5: - updated comment block on VirtioPciDeviceRead() - return EFI_UNSUPPORTED instead of failed ASSERT() in VirtioPciSetPageSize() - VirtioPciIoRead(): restore the original requirement that FieldSize equal BufferSize exactly (not only divide it). The looping added in v4 did not match the comment block, and the only place that used it in v4 (ie. VirtioNetGetFeatures()) needs an open-coded loop anyway (will be done in a later part of v5).
