This function was never consumed by drivers, and the current prototype is
unsupportable with virtio-1.0. Remove the function from the protocol
definition, and drop the current (unused) implementations.

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.

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).
