Pleae just drop the code - we should not add new drivers with custom

I'm not sure there's another way to do this: this not a driver, it's a
software emulator that pretends to be an actual device. We can't
have the platform supply DMA ops here since the platform is a regular
x86 or whatever.
Yes, actually vdpa-sim does not depends on HAS_DMA. Maybe we can do
shortcut like dev->dma_ops = vdpasim_dma_ops;
Thanks
