drm/vmwgfx: Refuse DMA operation when SEV encryption is active TTM doesn't yet fully support mapping of DMA memory when SEV is active, so in that case, refuse DMA operation. For guest-backed object operation this means 3D acceleration will be disabled. For host-backed, VRAM will be used for data transfer between the guest and the device.
