Olivier Martin 56f65ed838 OvmfPkg: Make the VirtIo devices use the new VIRTIO_DEVICE_PROTOCOL
This change replaces the accesses to the PCI bus from the Block, Scsi and Net drivers by
the use of the new VIRTIO_DEVICE_PROTOCOL protocol that abstracts the transport layer.
It means these drivers can be used on PCI and MMIO transport layer.

v5:
- VirtioFlush(): update comment block in VirtioLib.[hc]; error code is
  propagated from VirtIo->SetQueueNotify().
- VirtioBlkInit(): jump to Failed label if SetPageSize() fails
- VirtioBlkInit(): fixup comment, and add error handling, near
  SetQueueNum() call
- VirtioBlkDriverBindingStart(): remove redundant (always false) check for
  a subsystem device ID different from VIRTIO_SUBSYSTEM_BLOCK_DEVICE;
  VirtioBlkDriverBindingSupported() handles it already
- VirtioNetGetFeatures(): update stale comment block
- VirtioNetGetFeatures(): retrieve MAC address byte for byte (open-coded
  loop)
- VirtioNetDriverBindingStart(): remove redundant (always false) check for
  a subsystem device ID different from VIRTIO_SUBSYSTEM_NETWORK_CARD;
  VirtioNetDriverBindingSupported() handles it already
- VirtioNetInitRing(): call SetQueueNum() and SetQueueAlign() for proper
  MMIO operation
- VirtioNetInitialize(): fix destination error label for when
  SetPageSize() fails
- VirtioScsi.c: fix comment block of VIRTIO_CFG_WRITE()/VIRTIO_CFG_READ()
- VirtioScsiInit(): fix destination error label for when SetPageSize()
  fails
- VirtioScsiInit(): call SetQueueNum() and SetQueueAlign() for proper MMIO
  operation
