In case device is constrained by IOMMU or guest is running under AMD SEV, input/output buffers provided to device (DataBuffer and SenseData) needs to be explicitly mapped to device by PciIo->Map(). To avoid the overhead of mapping/unmapping the DataBuffer and SenseData to the device for every SCSI requst (and to simplify code), introduce a single DMA communication buffer that will be mapped to device on initialization. When a SCSI request needs to be sent to device, the DataBuffer and SenseData will be copied from/to the DMA communication buffer as required. This will be done by the following commits.
