OvmfPkg/VirtioPciDeviceDxe: implement IOMMU-like member functions
The patch implements the newly added IOMMU-like member functions by respectively delegating the job to: - VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages () -> MemoryAllocationLib.AllocatePages() - VIRTIO_DEVICE_PROTOCOL.FreeSharedPages () -> MemoryAllocationLib.FreePages () - VIRTIO_DEVICE_PROTOCOL.MapSharedBuffer () -> no-op - VIRTIO_DEVICE_PROTOCOL.UnmapSharedBuffer () -> no-op Suggested-by: Laszlo Ersek <lersek@redhat.com> Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Tom Lendacky <thomas.lendacky@amd.com> Cc: Laszlo Ersek <lersek@redhat.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Brijesh Singh <brijesh.singh@amd.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Regression-tested-by: Laszlo Ersek <lersek@redhat.com>
